Bolts worked perfectly!😃. Make sure to get drill bits with cobalt. The Amazon “buy all 3” bits were terrible!

Used six per 2x6 board on my 5x10 trailer to attach to each steel angle iron floor joist. Pre-drilled with a 7/32 bit. Job was much easier than I expected.

I replace two trailer floors using these screws. I did have to drill a pilot hole before they would self tap. Only 1 of 50 snapped during the process. That's not too bad.Pleased with the purchase.

These were purchased to replace wood decking on my 16' utility trailer. All 96 drove properly through a 0.228" hole through wood and steel with no issues. No stripped thread or heads.

Super strong. Used 400+didn't have a single torx slip or break. Just make sure to predrill the right size and let the impact eat. Would suggest 1/2" air impact over battery if doing alot. Would burn up a battery impact.
