Julian I. ★★★★★

The square neck on these carriage bolts grabbed tight and didn’t spin when I tightened them into the wood deck, which saved me a lot of frustration. They were fully threaded and the zinc coating has held up well so far through a few rainy days. I’ve already used half the package for furniture repair

Eli ★★★★★

The zinc plating on these bolts looks clean and uniform, no flaking or rough spots. I used them to fasten a heavy gate hinge into treated lumber, and the square neck locked in securely without spinning. Exactly what I needed for the job.

Amelia ★★★★★

I needed 50 for a deck repair and these came fully threaded which saved me from having to tap anything; the zinc coating looks clean and durable.
