Customer Reviews (4.8 / 5 · 5 reviews)

Chloe B. ★★★★★

The square neck grabbed into the wood on my first try, no spinning or swearing involved. Fully threaded means I didn't have to hunt for a shorter bolt when my stack was a bit thinner than planned.

Eli ★★★★★

The zinc plating on these bolts looks clean and should resist rust well in outdoor projects. I used them to secure a heavy wooden gate and the threads bit into the wood firmly without stripping.

Joshua ★★★★★

The square neck under the head grabbed the wood instantly, no wrench needed to keep them from spinning while I tightened the nuts. Zinc coating looks clean and even across all 25 bolts, and the threads were sharp enough to start by hand.
