You misplaced a decimal place in the metric example, it should be m4 x 0.7 x 10 0.07mm is less than three thou in inches, or 364 TPI. In metric you can just use a vernier gauge (caliper) to get the size of a bolt and the drill for tapping - tends to take less time.

@michaelwestman6272 5 лет назад

As a rule of thumb.Drill diameter in metric threading is the thread diameter minus the pitch.Exempel: M5 pitch 0.8mm tap, 5mm - 0.8mm =4.2mm drill. And when you drilling and tapping aluminium it's a good idea to use some type of alcohol for lubrication and cooling.

@ChrisEllerby 5 лет назад

My solution to not having to worry about the size of a #2 screw vs 1/4" screws is to just use the metric system. Even though I'm in the US, I do all my CAD in metric and use all metric hardware. It just makes everything so much easier.

@robertlawrence9000 5 лет назад

True. Instead of cutting sizes in half it's natural for us to use 10s because we used to 10 digits. I'm tired of carrying extra tools because of 2 different standards

Wish this video was released a week earlier... anyway, got confirmed what I learned! ;-)

@SeanBZA 5 лет назад

Only time I actually use the 1/4 and 3/8 taps and dies for a purpose, instead of just using them because they were closer to hand than the M6 or M10 taps, or I had a wallowed out hole, and the metric threads were going to be weak for M6, and I did not want to use the insert on that hole.

Lest we not forget about the very important NPT thread series as well. Air, hydraulic, water, propane, NG, fuels of all kinds, liquids of all kinds ALL use NPT fittings. NPT= National Pipe Thread, and taps and dies as well as sizes should also be covered here. Great Tips video! Thanks for posting!! Zip~

@Jasters_Fear 5 лет назад

NPT is national pipe taper. National pipe straight is a thing. There are far more types of threads than what is mentioned in this video, including unified national threads that fall outside C, F and EF. Heck, class of fit isn't even mentioned such as 1/2-13 UNC 2A being a standard fit external.

@simongingras2903 5 лет назад

The formula for finding out the actual outside diameter of numbered screw threads is quite simple. You need to remember only two numbers, .013" and .060". A no.0 screw is .060" od. A no.1 screw is .060" + .013" = .073" outside diameter. So on so forth for all the numbered screws. Following that reasoning a no.10 screw would be .013" x 10 + .060" = .190" outside diameter. Pretty close to 3/16th of an inch (.1875") which is why sometimes you'll see no.10 stove bolts being called 3/16". It also works in reverse for the aught sizes: a no.00 size screw would be .060" - .013" = .047" outside diameter. The smallest I've ever seen is a 0000-160 UNS screw (.021" od). The UNS in this case means United National Special; any screw thread that is not part of the Coarse or Fine series but still follows the United National thread form will carry the Special designation.

Using a drill press is the best way to get a straight cut but make sure to invest in a spring loaded tap guide, you mount it in the chuck of the drill press and the spring loaded tip slips into a hole in the back end of the tap, make sure to keep lowering the drill press as the spring unloads as the spring is all the down pressure you need.

@goodun6081 5 лет назад

In the US, #10 machine screws (bolts) is probably the commonest area where things get weird and deviate from the norm (see what I did there?). A number 10 bolt can often be found in either a 24 threads per inch or 32 threads per inch version, ie: 10-24 versus 10-32. Smaller diameter bolts and machine screws are only rarely seen in anything other than the one commonest thread, which, in my experience, are 2-56, 4-40, 6-32, and 8-32. 10-32 is the commonest, but the 10-24 size is used on a lot of things as well.

Thanks for presenting this information, I believe I already knew all of it, but a refresher course can't hurt, and helps teach those who don't. One item it would have been nice to mention: left-hand threads! They aren't used very often, but are essential for things like turnbuckles (one screw eye is right-hand thread while the other is left-hand). You'll also run into them in weird places like the wheel lug nuts on one side of a 1958 Pontiac (I don't recall if it was the left/driver side that were left-hand thread or the right/passenger side. Made it interesting trying to unscrew them until we found THAT out!). Maybe you could include them in a follow-up video about extracting broken or stripped screws and bolts.

@SeanBZA 5 лет назад

now you need to do a series on thread repair using inserts, and also roll taps for aluminium and soft materials, that do not cut threads, but make them by plastic deformation of the substrate. Much better than cutting, as it leaves the thread stronger than the parent metal, plus can be used in thin sheet with a much better thread being left.

@Doughiemantoo 5 лет назад

@goodun6081 5 лет назад

The flaw in those bolt- gauge plates is that I've never seen one that has actual threaded posts on them, corresponding to various thread sizes and pitches. It's quite possible to find a nut that slips over one of those plastic posts and assume that it's the right size for your application, only to find that although the diameter of the hole inside the nut is approximately or proximally correct, the thread itself is not! I modified one of my plastic bolt gauges by mounting a series of internally threaded standoffs/couplers to it, both metric and SAE types, with a cutoff bolt used as a threaded post on one end and the internally threaded socket on the other end, so that I can actually thread the bolt into the "known" coupler or standoff to check the thread; and I can thread a nut onto a piece of "known" bolt to see if it matches that thread.

@classicbandgeek 5 лет назад

Have you considered adding a power tapping head for a drill press, Sean? They usually work on a clutch so you're much less likely to break a tap and can be reversed when you bottom it out! As a machinist apprentice, I've found them pretty handy for deeper and large diameter holes that are just a bear to do by hand. Also - Helicoils are GREAT for re-tapping softer material like aluminum when drilling out the old threads and retapping just isn't an option.

@goodun6081 5 лет назад

It might have been a good idea to mention "screw cutters" in this video. Most cheap electrical crimpers will have screw cutters built into the handle, usually from 4-40 or 6-32 up to 10-32, and designed to give you a clean cut off edge on the shortened bolt so that it will still start the thread easily.. Not so easy to find a metric version of those in a regular hardware store, however; I need one and I'll probably have to buy it online, likely costing three or four times as much money as the SAE version.

Coarse are stronger in a strip situation. If you dont have much of the thread in the nut and you have a pulling force on that you want the strongest and thickest thread available material. He also dident talk about the grades of nuts and bolts. (hardness)

@daveansell1970 5 лет назад

If you are tapping a soft material like aluminium or plastic the resistance to stripping is particularly useful. A course thread is also much harder to cross thread as you need much more inaccuracy in angle to get a thread out. This is why camera threads are so easy to cross thread. Fine threads can be better in thin material if a course thread would have very few turns in the material

@Achtung73 5 лет назад

When the pitch is not specified on metric threads it is normally medium, not coarse. The pitch of the medium is about 15% of the diameter.

@hippieengineeringworks2310 5 лет назад

There's no such thing. Maybe you're thinking of tolerances, which go from Fine to Medium to Rough? Coarse metric threads are always the largest standard pitch for a given diameter, such as 0.75 for M4 and 1.25 for M8, anything less will be Fine.

@ZippoVarga 5 лет назад

As for using Dies to correct threads, you're better off using a thread file over a Die if you don't have the proper thread restore kit. Leave the Dies for new threads only. Again, great rudimentary explanation of a commonly misunderstood fastener. Zip~

@theonlyalan731 5 лет назад

The formula for figuring out number sized screws is .060" + the number of the screw * .013" So, for example, a number 10 screw is .060" + .130" for a total of .190" diameter. Number 0 is just 60 thousandths and as you add zeros from there you start subtracting 13 thousands. So #00 is .047", #000 is .034" of course these are the nominal sizes and the actual size is generally just a tiny bit smaller

Complements on the thread section the tap section needs a bit more work. I was surprised that you didn't mentioned the simple tapping guides like the Big Gator V-Tap guide and other similar tools. Machine tap taper forms are type A, B and C. Type A, a taper of 6-8 threads, the chip is thin and is brought upward into the already tapped part. Because of the long taper not very suitable for blind holes. Type B, a taper of 4-5 threads, it has a spiral point, breaks the chips and transports them down or forward into the hole, not suitable for blind holes. No need to reverse the tap for chip breaking. There is also a type B-AZ, mostly the same as a type B but on the upper 2/3 the cutting teeth are interrupted which make is very useful for long chipping materials like aluminium, magnesium, brons or plastics. Type C, a taper of 2-3 threads, Produces thick chips that are transported upwards, very suitable for blind holes and short chipping metals like cast iron. There is also a type C with a spiral chip groove for better transport of the chips, the downside is that there is less support for keeping the tap strait. btw When cutting materials like aluminium use kerosene or mineral spirits as a lubricant, WD40 also does a great job. Cast iron does not require lubrication.

For properly designate metric threads you'd use diameter x pitch x length , so your example should be M4 x 0.7 x 10. Dashes specify tolerance and handedness. Also, the pitch should never be specified on coarse threads. So for a coarse M4, you would put M4 x 10, never M4 x 0.75 x 10. For fine threads you can put M4 x 0.7 x 10 or MF4 x 0.7 x 10.

Of course if it's a small screw and Imperial you would have to look up what # it corresponds to. Also - if it's in plastic you want to look for 'electronics screws' or plastic tapping screws.

Anything that's in U.S. customary measurements is confusing. Good thing we have an international industry standard called "metric" where we don't need an entire equation just to figure out what kind of thread a screw has.

@captjaneway3 5 лет назад

You said screws go the 1/4" after #12 but I know there is also a #14 screw. How does that figure into the numbering system? Is #14 and 1/4" equivalent.

I found a nice shaft with thread on it how can I determine which thread do I have is it Metric or standard ?how to figure it out thank you

HELP! Where can I get an M3-0.6 x 30 oval or pan head machine screw? A #4-42 x 1-1/4” oval or pan head machine screw will also work.

@Leon-yt6dc 5 лет назад

normally you only need cutting oil for steel... plastics or aluminium are fine without ^^ and there are different thread cutters for holes that dont go through all the way they are twisted like a drill and transport chips better. the ones shown in the video are for cutting threads in holes that go all the way thorugh ^^oh and metric is way better than this inch stuff ,its just confusing XD

@goodun6081 5 лет назад

@ss , here in the USA, we actually see a lot of audio equipment with Posi-drive, or JIS screws, in the electronics repair shop I work for. Pozi Drive in particular are easy to recognize if you know what to look for ( we see them used in a lot of European made speakers and audio gear). And although I have been using hand tools for about 50 years, it's only in the last few months that I found out about JIS screws. I had just assumed that the little dot or divot In the screw-head meant they were metric thread or that the Phillips head of the screw conformed to some kind of differing metric specification, so I would search through my screwdrivers and screwbits to find one that fit snuggly so as not to chew up the screws. I'm not a motorcyclist, otherwise I might have found out about JIS screws earlier; apparently, some Yamaha and Honda motorcycles are famous for screws that strip easily when you go to remove the carburetor or otherwise do maintenance on the bike. I was actually working on a Yamaha amplifier just yesterday that had JIS screws in it.

@goodun6081 5 лет назад

@ss , thanks for the link, I will check it out. I've been familiar with posi Drive screws, also the square Robertson bits scene in Canadian equipment in particular, for many years. Never heard of Supa- drive or Frearson, however. It amazes me how difficult it can be to find information online about various variant screws, screwdrivers and screwdriver tips or bits such as these. About six months ago I started wondering why it was that I kept in countering Phillips type screws that weren't pozi Drive but most of the screwdrivers and screw bits I had just didn't fit them right. It took quite a while to find the info on JIS screws and screwdrivers. I guess if I was a motorcycle Rider or at home garage mechanic I would have found out about it sooner. Still, from the mid 70s up into the early 90s I was a car stereo installation Tech, doing all kinds of fancy auto stereo system installation, and although I was quite familiar with most metric fasteners, I never learned about the JIS screws.

When drilling a metric thread subtract the bolt size from the pitch and it will give you your hole size

@martinj.9528 5 лет назад

Paul Smith that makes sense, but would that mean having to drill a 3.3mm hole for an M4 bolt (if it is .7 pitch)? I haven’t seen a 3.3mm drill bit in any of my sets, just the 1,2,3,4mm... Is it something you have to buy separate?

So... fine is better in every way, but coarse is more common. I'm guessing it's because coarse is somehow easier to manufacture?

All I know, is that every time I go to the store to get a matching fastener, I'm screwed because nothing matches the threaded part that I bring in with me. Or, they're out of stock, and will continue to be, for the next 15 years.

Find a Fastenal or other industrial supply house store. The home improvement warehouse stores only carry some of the common types, and have poor selections of hardware under 1/4"

@fetalmistake5624 5 лет назад

You got the naming of Metric Screws wrong! Metric screws usually do not have the pitch in the name because the different sizes have different pitches that are predefined. As soon as the pitch changes from the normal ones it is designated by a letter in the name.
