Customer Reviews (4.6 / 5 · 5 reviews)

Daniel A. ★★★★★

Put these on a pergola project where the exposed heads need a clean look, and the 316 stainless is holding up to coastal humidity without a hint of rust. They drove in smoothly with no stripping on the threads, which is exactly what I hoped for.

Charlotte A. ★★★★★

The square neck grabbed the wood immediately on my fence gate, so no spinning or stripped frustration while tightening. The 316 steel finish looks clean and the full threading made alignment effortless. These will definitely outlast the pressure-treated lumber they're holding.

Harper ★★★★★

Installed these on a new dock repair and the square neck held perfectly without spinning while I tightened the nut. The 316 stainless feels solid and should resist corrosion much longer than the old zinc ones.
