Customer Reviews (5.0 / 5 · 5 reviews)

Ruby ★★★★★

The zinc plating on these bolts looks clean and should resist rust well. I used them for building a heavy-duty gate, and the square neck kept them from spinning while I tightened the nut. Solid hardware for the price.

Natalie J. ★★★★★

The square neck grabbed the wood instantly on my first test piece, no spinning at all once I tightened the nut. Zinc coating looks clean and uniform across all 25, and the threads are fully cut so they started smoothly without any binding.

Olivia ★★★★★

Needed to replace some old, stripped-out bolts on a wooden gate, and these carriage bolts were perfect. The square neck underneath the rounded head really does grip the material and stop the bolt from spinning as you tighten it.
