Kevin H. ★★★★★

Installed these on a dock gate last weekend and the square neck kept them from spinning when I tightened the nut. The 316 stainless seems like it'll hold up way better than the zinc-coated ones I used before.

Brian T. ★★★★★

I needed a longer bolt for a marine railing repair, and these 7-inch 316 stainless carriage bolts are perfect. The smooth, rounded head looks great against the wood, and the partial threading made installation simple.

Brian ★★★★★

The square neck under the head grabbed the wood instantly, so I didn't need a second wrench to hold them still while tightening. The 316 stainless finish looks clean and should handle the outdoor deck project without any rust worries.
