Customer Reviews (3.6 / 5 · 5 reviews)

Charlotte I. ★★★★★

These bolts fit perfectly into the pre-drilled holes for my deck railing, and the square neck grabs tight so nothing spins when I'm wrenching the nut. The plain steel finish is about what you'd expect from a workhorse fastener, but they held up fine during assembly.

Harper J. ★★★★☆

The square neck really grabs hold as you tighten it, which saved me from having to use a wrench to keep it from spinning. For the price, you get solid plain steel bolts that do the job.

Owen E. ★★★☆☆

I used these for a deck repair and they did the job, though the plain steel is already showing some surface rust after a few weeks. The square neck pulled into the wood effectively, but I wish the heads had a bit more grip.
