Deck Screw Brands: GRK, SPAX, Deckmate, Woodpro, Deck Drive, FastenMaster, PowerPro, Grip Rite, Deck Plus, Velocity, and Eagle Claw. Screws tested for abrasion and corrosion resistance, holding strength, and shear load. My goal is to always provide accurate and honest test results by avoiding outside pressure from manufacturers. To do this, I always buy all of the products that I test along with the test equipment and supplies used for the testing. So, thank you very much for helping me achieve this goal by your support of the channel.

I usually end up binging 3-5 videos in a go and every once in awhile I watch one of his older videos where he's seeing how quickly he can blow up a harbor freight motor with cruddy oil substitutes. And even those videos allow me to appreciate how his dry humor and video editing have transformed and polished through the years. Because I'm the same as you, I've been subscribed for years now and his changes have been subtle and yet transformative. I didn't subscribe to a dude who compares all that crap in your garage, instead I subscribed to a relaxing, informative and yet entertaining guy and he ended up doing comparison videos.

There's actually a very interesting story about the grk screws. The original owner made sure they were manufactured in either the US or Germany, and eventually brought the majority of manufacturing here to the US. Eventually one of the evil Omni mega corps bought him out, but the terms of the buy out stated the US manufacturing had to remain open. The new owner violated that, shipped manufacturing to Taiwan, and the quality took a massive crap. However, due to them violating the terms of the agreement, the original owner, with hundreds of millions of dollars, opened u2 fasteners built to the same original standards with a few new improvements to design and production. Ran grk out of town in the northwest. And brought American manufacturing back. This all took place around 2016

@randysmith9636 2 года назад

Personally I use Spax after using a few different brands. I found that over time the Spax stayed tight better than others. Having a screw stay in place, for me anyway, is more important than a little extra effort to install. I have only used SS one time and that was on a dock. They did excellent during the build but after a season I had to go back and tighten most of them down. Of course alot of it is from wood shrinking especially with pressure treated. I did use Spax on a redwood one time from customer request. I told him that I would not guarantee that it wouldn't discolor at every screw point. Two years later it still had not discolored hardly any at all. Only a couple areas had a very slight discolor. Of course I pre drill everything with a counter sinking bit so that helped I guess. All structural gets galvanized ring shank by hand, never cared for a nail gun for build decks. But over all Spax has proven to be a extremely good deck screw. The cost is only slightly more than deck mate but the over all performance is well worth it. Thanks again another great video, I honestly look forward to getting that notification from you. Keep up the great work, it truly does help us make a informed decision.

@grizzlygrizzle Год назад

I always make sure to have some Fastap and Fastap Plus screws on hand. They have a unique tip that cuts a somewhat bigger hole, and they are good for going into harder woods, or where you need to screw farther into wood to the point where the torque required would be enough to snap other screws. Their coated screws were developed for salt water docks. They are more expensive than other screws, but their unique tips allow them to do the job where other screws won't, or require pre-drilling. They're hard to find in stores, so I get them online.

@doitright8150 11 месяцев назад

There's no substitute for stainless steel. We have a deck next to a swimming pool that is outdoor-carpet-over-wood decking. No metal screws have held up like the stainless. We typically get about 5 years out of the carpet before I need to replace it, and I will replace some deck boards as well. The s/s screws are always easily removed and I can reuse them; the same never applied to metal screws regardless of their "ultra-tough ceramic coating". Even hot-dip galvanized screws didn't last. They may cost 3x as much but def worth the investment.

@TheMrAHead 2 года назад

In my experience, those coatings are simply for the color to match whatever your final finish is. It may also provide a little bit of lubrication on the way in. the corrosion resistance comes in the type of metal used in the screw.

@ProjectFarm 2 года назад

Great point! Thank you

@TheMrAHead 2 года назад

I use the GRK screws for absolutely everything interior and exterior. I used to keep interior and exterior screws but that turns out to be way too many different boxes of fasteners.

@T3sl4 2 года назад

Speaking as an engineer, I'm impressed that the variances are as small as they are. This tells me, you can't go wrong with deck screws -- plan for loads a modest fraction of the failure point and any will handle it. That just leaves individual variation in stuff like coating quality, and, the elephant in the room, consistency of the wood being driven into (which from other data I've seen, looks to be much worse!). Nice to see a stainless screw on here, I'd think those are fairly specialty (coastal salt spray, industrial environments?), shame they apparently aren't as strong but to me that's just a compromise for using something exceptional otherwise.

@ProjectFarm 2 года назад

@markmmm1737 2 года назад

I wouldn't say they are weak though. I am quite shocked at the sheer strength of a single screw. I was worried about pulling myself up onto a walk way overhead beam I fitted in the garden using 2 screws just in case my weight broke the screws holding it in. I am not 600kg so now I know that I don't need to worry, the wood may break though hehe.

100% no on stainless. Bought a home with composite decking, ribs under neath rotted out. We could not get stainless screws out they all stripped out. Had to pry board up and remove the screws with channel locks from the bottom. Turned that several hours job into 2 days!

@T3sl4 2 года назад

@@brianx2640 Rough! Yeah, that's a huge pain, just from the material being a little bit softer probably. Normal screws I think are heat treated 1050 or so steel, not so hard like tool steel but much stronger than mild (have rounded off many a wood screw, the traditional tapered kind, man those things suck!). That's why they bend a little, then snap. 305 stainless can only be work hardened, not heat treated, so it would figure the screws aren't as hard. Next best thing would be a PH stainless, probably? Might be too expensive for deck screws though.

@@PW98372 glad to help! Any "deck" screw from the local hardware store that is rated for pressure treated wood works great. I would recommend staying away from Phillips screws and going with square drive or star/torks drive (6 point star). These screws usually come with the correct bit in the box.

Unfortunately, it's not actually that informative. This is highly anecdotal testing: at best this is entertainment disguised as "science". Maybe PF found three good or three crap screws from each brand: maybe you can see the random "black swan", but you probably won't A minimum of 29 samples per brand would be genuine scientific testing. That way you can determine a minimum confidence level for average statistics, deviations, variance, and derived statistics. It tells you nothing about the average screws from each brand or the brand overall. Funny enough when a tool test channel torture tests a drill or impact driver and drives hundreds of screws, they are inadvertantly doing a proper level for sample size on the quality of screws, but they aren't usually thinking of testing for torque specs for the screws, etc.

I've been using GRK and Spax as my primary screws for years now.

Generally Spax is my go to all rounder for 2"-4" with GRK being my choice for their smaller and lag bolts. Sometimes it is worth that bit of extra money for consistent performance.

I used 6" long SPAX to anchor my ledger boards. A combination of screw design and the coating made it easy to drive with a 1/4" impact. NO Pre-drill, NO Splitting.. No way would that work with an old-school lag bolt even with a pre-drill.. AND Building code allows a smaller diameter SPAX than a Lag-bolt for the same application..

@DannySauer 2 года назад

I switched from Grip Rite to Spax and GRK several years ago for several reasons, mostly structural rating and wider variety available. This fall, I removed some of the Grip Rite screws I installed in some cedar 11 years ago, and they still looked nearly new, but all the GRK screws outside also still are reusable. Like you said, I don't thing I've ever broken one of either GRK or Spax, and maybe one has come out of thousands driven with a defective drive hole. I like the extra drive nub that stabilizes the Spax screws, but the GRK are a little easier to find, and maybe start just a little easier. So I mostly use GRK for "construction" screws where the head will get sunk into the surface, but Spax for washer-face cabinet screws and lags. The lags from both companies are also great - soooo much easier to drive than traditional lag bolts, *and* no need to pre-drill.

Great job as always. As the winter season ultimately falls upon us, I suggest testing sidewalk salts. The price varies wildly amongst the brands. Even more curious is how something like water softener salt stacks up being it's roughly 1/4 the cost. It's price blows my mind because it's washed and cleaned, certified for human consumption, while what is available to throw on your sidewalk is far more expensive...

@workingguy6666 2 года назад

Sidewalk salt is an interesting subject. If my father were still alive, he could give anecdotes on what all he saw as a concrete and salt (during the winter) salesman. Basically the suppliers of the salt can vary widely even though the branding on the outside of the bag will be the same year after year. He had stories of calcium and other ice melts, and the nuances of such (like damage to surfaces, etc.). Wish I could recall them now. My guess is that the only ones that could be tests would be the processed / manufactured ones, as salt quality varies from place to place.

I use water softener salt. 40lbs for less than 1lb of "sidewalk" salt. Salt is salt, and while we do get extreme cold of -30f or colder that's not when you get ice. We get ice when it's 15-20* or warmer and it makes zero difference what salt I use. Grass doesn't seem to care either.

Interesting enough, it's been my experience that what inventory is at Lowe's is a store by store issue. I've found GRK, SPAX, Grip-Rite, and DeckMate screws at different Lowe's in my area, some with have any, all, or some of them; but you almost have to do an inventory check online (or in store) to be sure if that particular store will have a certain brand. This may also be an issue of the luxury and privilege of living in Orlando whee we have at least a dozen Lowe's (and another dozen HD) within an hour's drive; results might be radically different where Lowe's is a scarcer store. Purely for entertainment purposes, it might have been nice to see how the Hillman brand regular and premium deck screws fared

@IceInMaWeiner 2 года назад

Definitely one of the best channels on youtube! Suggestion: It would be nice to see comparison charts on which screw would be best for which application ex: for low-corrosion environments this is the strongest bang for your buck, for reduced drilling time & effort this screw is great for lightweight projects. Sometimes it's not only about best-of-the-best. I guess what I'm trying to say is it could be helpful to compare related charts before the final conclusion.

@user-lt6oh2bu7c 2 года назад

After watching the deck screw reviews I have to ask: have you considered testing composite deck boards? I currently have a bunch of people asking me which one to buy, all because of a brief comment on the Nextdoor app. Around here (Houston) we have intense heat and tons of rain and wood just doesn't cut it. Pretty much everyone with a wooden deck, dock, or walkway wants to or needs to replace it with composite. Along with composite we're all looking at aluminum, plastic, and the Weardeck fiberglass (a leading contender). Man would we love to see you do your thing on all of these options!

Interesting results! It will definitely have me looking closer at my normal deck screws when I remove them from temporary projects. I already had the unpleasant experience of removing SPAX deck screws that were maybe 10 years old: they held up much worse than whatever other brand the previous owner used (it was a less distinctive design) - nearly all the SPAX corroded and either stripped out the head, or the head snapped off. For those I could remove, they were far more eaten away than the other brand. I definitely won't be buying any. I've had some of the larger GRK structural screws, and they hold up well so far, including in reuse.

@davep2945 2 года назад

After building dozens of decks, installing cabinets, building raised beds and installing various structural and non-structural elements over the years I by chance settled on GRK and Spax and the go to's with Grip RIte as the third alternate. Fortunately most people won't pay extra for the GRK or Spax screws so they always seem to be available. A bonus by default. The only issue I ever had with Grip Rite was the higher rate of unusuable screws due to excess coating application clogging the drive slots. And the rare shearing of the head when driven into harder, old wood. Maybe that's not a factor now but I can't remember a GRK or Spax screw shearing off. I'm sure it happened but not often enough to stick with me.

@ProjectFarm 2 года назад

Thanks! Thanks for the video idea.

@ThatGuy-sd3zl 2 года назад

As a mechanic, I use torque sticks all the time. No, they are not very accurate but I still prefer them to torque wrenches. I’ve never lost a wheel with torque sticks but have lost one using a torque wrench. Also when customers come in with loose wheels, it’s often due to tire shops using torque wrenches. I have no problem with techs using torque wrenches, but it’s crucial to retorque them after 100kms or less. With torque sticks I haven’t ever had to retorque a wheel. A torque stick typically torques more than what it’s rated for. But this also is effected by the torque output of the impact. Air and cordless make a difference and the blows per minute of the impact makes a difference. A wheel I’d say seats better to the hub using torque sticks than it would with a torque wrench. It also saves a lot of time.

@keepingdistance4404 2 года назад

@@ThatGuy-sd3zl No way I'd trust final torque to a torque stick. Too dependent on air line pressure and gun settings. They are fine for limiting the gun's torque, but final torque needs to set with a torque wrench. Question: Would you final torque the engine head bolts with a torque stick?

@rockyrococo2584 2 года назад

Yeah,this exactly. They aren't very accurate but they have a time and place and they depend on being matched to the right impact set up. They're great for things like rims and frame mount hradware but are a disastrous or at best poor choice for actual torque specific critical things like engine ead bolts. Actaully anything on the actual engine torque sticks are bad choice.

@somejoe7777 2 года назад

Ya, I don't use them for the final torque -- always use a torque wrench for that. What I find them useful for it to prevent over-torqueing wheel nuts when reinstalling a wheel. If torque spec is say, 100 ft-lbs, I put a 90 ft-lb torque limiting extension on the impact driver and install all the nuts, then go back with a torque wrench for the final 100 ft-lb spec. This makes sure that I don't over-torque the nuts using the impact driver.

I'd say the most important aspect is corrosion resistance. In reality if you use any of these in a building project, you're going to have sufficient strength. But whether or not the project lasts for 30 years is pretty much solely reliant on if your screws rust out and give up or not.

I'd like the thoughts of others about pre-drilling with these screws. Many say they don't need it, but I have found that taking the time to make pilot holes really makes for a cleaner result that seems to stay tightened for longer. Is this just chance (or a myth), and is there a science with how the wood fibers work with the fastener with and without pilot holes?

@mbfhh 2 года назад

100% agree. I wonder this every time I have to drill more than a handful of pilot holes. Assuming no splitting, is no pilot hole the strongest fastening strength and longevity? If not, is it better to drill a pilot hole just smaller than the shaft excluding the thread diameter? And how big is the difference?

@stevesether 2 года назад

I replaced al the decking on my deck in 2009 with 2 x 6 inch treated wood. 13 years later and there's no splitting, and they haven't loosened. And this is on treated wood, which of course will shrink a little. I couldn't tell you with other types of wood if you need pilot holes or not. There's been a small number of pieces that have rotted due to carpenter ants, but that's the only maintenance issue I've had.

@ProjectFarm 2 года назад

@stevesether 2 года назад

FWIW as a result of wood rot, I replaced all the decking on my deck in 2009 with treated wood. The old screws were horribly corroded (I don't think they even used coated screws), so I wanted to make sure the same thing didn't happen. So I bit the bullet and bought stainless steel screws. The deck is in a shady location, so dampness is an issue, plus the winters here are harsh. 11 years later I had to disassemble part of the steps to route some gutter drains underneath them. The screws had no visible corrosion. Same story on some other boards I removed and replaced from rot from carpenter ants. I'd say sulfuric acid is a shade too aggressive of a corrosion agent against stainless.
