S-WM12212G250 Screw, 12 x 2.5, Steel

These worked well for attaching pressure treated lumber as decking onto a trailer made of 1/8" steel. Probably about one out of ten dulled before tapping through the metal.

worked greathad to predrill a hole on the 1\4 inch metalbut was 3 days late

Worked great for re decking my car trailer. Threads are only 1.75" long but bite good when sunkinto the 2x6. Would be a little better if screws were a little longer like I expected.

Re-decked a dock with pressure treated 2 x 8 pine over a frame of 1-1/2 x 1-1/2 x 1/8, hot dipped, angle iron. Roughly 10% of these fasteners burned themselves out just penetrating the pine. They lost their temper, their hardness, and were unable to drill into the steel.

I used almost the whole bag (250) attaching wood to my steel framed building. they work great but I should have ordered 2-3/4 inch long to attach 2X4's to steel. I had to countersink 1/2 inch for these shorter screws

Only broke one screw in a box of 300 and that was going through way more letters than I should have been trying for

Works great for attaching new boards to my 16 foot trailer. Fast

I gave this screw a 5 I have used many screws in my life to fasten wood to metal I have never used anything that compare with it , top of the line product
