Customer Reviews (4.2 / 5 · 5 reviews)

Harper ★★★★★

The square neck on these bolts grabbed hold of the wood immediately as I tightened them, no spinning or slipping at all. I've been building a heavy-duty workbench and the fully threaded shank gave me a real solid grip through the 2x6s.

Adam N. ★★★★★

The square neck locked perfectly into my trailer's wood deck, and these bolts didn't strip when I tightened them with an impact driver. The full threading made for a solid grip through the steel brackets.

Christopher T. ★★★★★

The square neck under the smooth head seats perfectly into the wood, so these 400 carriage bolts never spun while I was wrenching the nuts down. For plain steel A307 grade, the threading is clean and consistent across every single one I've used so far.
