Extra sturdy and the washer head keeps your screw from sinking through without pulling the boards together like deck screw tend to do. I’m building a barn with them and haven’t regretted using them. Fantastic product for a low price.

I want something to hold down my 2x6 deck boards on my deck. THEY ARE IT. Enough though these are made to be driven without a pile hole, I DID NOT. I always do pilot holes for critical stuff. Have less problems with a board lifting away from a board I am mount to. I know I am Anal (perfectionist). But I want it to last a lifetime or more, I hate shotty workmanship. There are TWO pluses to this screw, one is the large head on it, better than those traditional deck (bugle head) screws where it splits the wood some of the time. And after two years, the deck boards are still tight. The second in their pull and shear strength, especially if you need to tied down something heavy on the trailer. Screws on the deck are just as important as D-rings and your straps.

These screw in easily without a pilot hole and really pull the wood tight. I prefer the bolt head, but these are better for flush mounting behind joists and such.
