Chloe ★★★★★

The square neck on these 316 bolts really bites into the wood, so I didn't need a wrench to tighten them. They're fully threaded, which gave me plenty of grip for a thick project. Good to have a full pack of 200 on hand.

Adam ★★★★★

Finally got around to mounting some outdoor shelving, and these carriage bolts sank perfectly into the pressure-treated wood without spinning. The square neck really does its job, and the 316 stainless feels like it'll hold up much longer than the zinc-coated stuff I used before.

Ruby ★★★★★

Needed a solid stainless option for a dock repair project and these carriage bolts fit the bill perfectly. The square neck really does grab tight into the wood, and the 316 stainless feels like it'll hold up to saltwater for years.
