Sophia V. ★★★★★

I needed exactly this length for a deck project, and the zinc plating on these carriage bolts looks clean and should hold up well outdoors. The threaded portion was consistent all the way down, making it easy to get the nuts started by hand.

Mia ★★★★★

The square neck really grabbed into the wood and kept these from spinning while I tightened them down. No stripped heads or wasted bolts out of the whole box, which saved me a trip to the hardware store.

Andrew ★★★★★

Used these to mount a heavy wooden gate to metal posts, and the 6-3/4" length gave plenty of bite into the frame. The zinc plating hasn't shown any rust yet after a couple rainy weeks. Solid purchase for the price.
