Customer Reviews (4.6 / 5 · 5 reviews)

Lucy B. ★★★★★

The square neck grabbed perfectly into the wood on my trailer frame, no spinning at all while tightening. Zinc coating looks evenly applied and should hold up fine outdoors.

Abigail C. ★★★★★

These bolts fit perfectly into my metal project, and the zinc coating looks clean and consistent across all 300 pieces. The square neck locks in tight so nothing spins when I tighten the nut.

Ryan L. ★★★★★

The square neck on these carriage bolts really locks into the wood, so I didn't need a second wrench to tighten them—huge time saver. The zinc plating looks clean and should resist rust well for outdoor use. A solid 300-count box for the price.
