Customer Reviews (5.0 / 5 · 5 reviews)

Adam ★★★★★

The square neck grabbed the wood immediately when I sank them into my deck frame, no spinning or fussing with a wrench. 316 stainless is a relief too, since these are going to sit outside in the salt air.

Eli ★★★★★

These bolts tightened up perfectly on my dock repair, and the square neck really does lock them in place without spinning. The 316 stainless feels heavy-duty and should hold up well by the water.

Ella ★★★★★

Tackling a boat trailer rebuild and the square neck under the head on these is a lifesaver—it really grabs the wood and makes tightening a breeze. The extra corrosion resistance from the 316 stainless was exactly what I needed for the saltwater environment.
