Victoria B. ★★★★★

These carriage bolts are perfect for saltwater deck work, the 316 stainless is holding up noticeably better than the 304 stuff I used last year. The square neck grabbed solidly and didn't spin at all when I tightened the nuts, saved me a lot of frustration.

Adam T. ★★★★★

I was replacing some dock hardware and these stainless bolts didn't show any rust after a week in saltwater spray. The fully threaded body made installation much easier than the partial thread ones I’ve used before. They feel solid and the rounded head sits flush against the wood.

Ella ★★★★★

The square neck grabbed immediately when I drove them into pressure-treated wood for a fence gate. No spinning or slipping like cheaper bolts. 316 stainless should hold up beautifully in this coastal weather.
