This is an excellent demonstration. I have never used these screws before, and I knew very little about them. But I will definitely be getting some in the future.
I agree with David T - In my experiments the drilling process was painfully slow, needed lots of effort, & difficult to control speed even on 2 speed drill. Yes I was using 14 g Teks in 2mm steel on an RHS. Frankly I found it easier to drill a pilot & the use the self drilling screw. Your screws performed like HSS drill bits!!
Putting a socket extension directly into a drill chuck is not the preferred way to drive hex head screws, though in a pinch, you gotta run what ya brung! I nut driving bit of the appropriate size (usually 1/4, 5/16, and 3/8 will do) or a hex shaft bit with a square drive end, available in 1/4, 3/8, and 1/2 sq. drive size) stuck into the socket extension works too. And it gives you the added flexibility of driving any size socket you've got. The problem with the extension in the chuck is that it's round and can spin if it hits resistance, halt the driving force not to mention chewing up the extension pretty good.
Man, you're using some really good quality screws there. A pleasure to watch. Most of the self-tapping screws sold here (USA) today (cheap, crappy, soft metal) wouldn't go through most of that material, even the smallest stuff, without very quickly stripping or snapping off. By the way, I have the same Dewalt drill.
they are extra efficient and handy. you can drill tough metal thick as drilling point on the screw, soon as thread catch you will lose gripping metal and even if you drilled through that 4cm metal bar, there will be nothing left for screw to grip on. only if you get thicker screw after and use it in that hole... when installing door closer and have to drill in to the metal door frame, i use only those screws because drill bit get dull quickly.
Great video and thank you purchased the 1 inch self drilling roofing screws with hexagon head and needed a refresher for tool set up. Previous to this mostly used Philips head screws. ✊💪🙏👍
6:10 - after two minutes of drilling that screw would be sooooo hot that you would not be able to touch it at all. But great video and great screws, that stands for sure :-).
Aluminum is not considered a heavy metal, for heavy metals you wanna keep the drill on speed 1, an drill slowly (dont squeeze trigger all the way) ,but add ur body weight for pressure!! So for Aluminum I'd keep it at speed 1, an just squeeze the trigger, not much body weight (pressure) needed since its softer metal.
You should use a screw gun and not a drill. It's too easy to break the heads off with the drill. When I was in High School I used those screws by the 50 lb. box full.
@@antoniorivera1311 it worked perfectly, I used 3mm play and it's thick enough to walk on. These screws screw straight through into aluminium with ease.
@@antoniorivera1311 the only thing I'd make sure of is that the wood is heat treated and not chemical treated, because any chemicals could leech into the metal and cause rust
