Customer Reviews (4.4 / 5 · 5 reviews)

Ava ★★★★★

The square neck grabbed instantly into the oak beam I was mounting—no spinning at all during tightening. All 100 bolts threaded cleanly with no burs on the zinc plating.

Julian ★★★★★

Had to build a heavy-duty playhouse for my kids and these carriage bolts were perfect — the square neck really bit into the wood without spinning, made the whole job so much smoother.

Lucy I. ★★★★☆

The zinc plating on these bolts looks clean and even, and they fit perfectly into the predrilled holes in my deck project. Only minor complaint is the threads could be a tad smoother when starting the nut, but they tightened up fine.
