The serrated thread on the end helps cut the wood instead of breaking it, the smooth portion allows the plank to pull itself toward the joists, and the square shank keeps the blade from popping out like the Phillips heads do on me do. I decided to buy stainless steel screws when I was replacing some decking boards and the regular decking screws I bought from Home Depot or Lowes were almost completely…

I was working on a set of ladders when they arrived and had drilled and screwed 3 stringers many times that day so I had a pretty good idea of the wood hardness and performance. This has never…

When I got home and used them it was clear that they were a huge improvement over the cheap props I had used in the past. Two things set them apart: 1.
