Customer Reviews (4.4 / 5 · 5 reviews)

James W. ★★★★★

I used these to replace some rusted bolts on a boat trailer, and the 316 stainless steel held up perfectly in the saltwater. The square neck grabbed the wood immediately, making installation a breeze.

Nicholas U. ★★★★★

Installed these for a dock repair and the 316 stainless is already showing much better corrosion resistance than the cheaper zinc ones I used to use. The 12-inch length was perfect for sandwiching two thick beams together securely.

Jacob O. ★★★★★

The rounded head sits flush without snagging anything, and the 316 stainless feels heavier than the standard zinc ones I’ve used before. These 12-inchers held a deck frame together with zero shifting even after a week of rain.
