Customer Reviews (4.6 / 5 · 5 reviews)

Eva ★★★★★

The square neck under the head really locks into the wood on my deck rebuild, and the zinc coating looks clean. I ordered the 375-pack and every single bolt threaded smoothly without any duds.

Zoe A. ★★★★★

The squared neck under the head really grabbed and held tight in the wood without any spinning. These zinc-plated bolts cleaned up easily and should hold up well against the weather on my outdoor bench.

Brian ★★★★★

I needed a full box for a deck project, and these fully threaded carriage bolts have the square neck biting perfectly into the wood so they don't spin. The zinc plating looks good and should hold up fine outdoors.
