          These were what I needed to attach 2x3 studs, with liquid nails, to the corregated surface of a shipping container so we could skin it with plywood for a smooth surface.

          Still a Workout!
          Went through 3/16” channel trailer frame, require good amount of force/body weight, (190lbs), pre drilling 2X8 PT lumber helps, IMO no time savings over drilling steel and using self tappers, benefit is cost savings and availability, still a lot of work.

            they sucks
            I try to use them on my utility trailer to hold my 2x6 and I have to pre drill a hole to the wood to make them work.. also half of the screws must up half way when they drilling to the pre existing holethey come 40 on the box and more of the 20 mest up before they reach the head of the screws

              Perfect for attaching 2x wood material to steel framing
              I used these self-drilling, self-tapping screws to replace the pressure-treated pine decking on my hauler. The hauler uses 3/16" thick steel for its frame. These screws are coated and rated for exposure to the chemicals in pressure-treated wood so they won't corrode as most fasteners do in that application. I used a cordless drill/driver to install the screws, and every screw worked perfectly, drilling first through the wood, then the steel, and then tapping its own threads in the steel. Couldn't be easier or simpler. And of course these screws are intended to also self-countersink, leaving a completely smooth finished surface which is necessary on a trailer deck.

              I needed to replace the decking on the 8' x 12' utility trailer I built some years back. I originally used 3/4" plywood sheets stacked 2 thick for it but this time I used 2" x 8" treated lumber and needed something that would hold them down and still be easily removed in case a board got damaged. I was going to drill pilot holes and use screws but didn't think they would hold up to the stresses. Them I found these and it was PERFECT!!! They have a large head to support the boards and most important they were self tapping. My son and I attached all of them in less than 90 minutes and it is stronger than ever.

              This product worked perfectly for attaching wood fence pickets to 14 gauge structural steel tubing in a single step. The little wings bore a clearance hole through the wood and then break off as the screw drills/taps the steel. I was initially concerned that the phillips type drive would be a problem but the bit supplied with the screws fit the screw heads well with absolutely no slippage. This is a great product for attaching wood to steel!
