Claire G. ★★★★★

The square neck under the head grabbed the wood perfectly on my deck frame, so I didn't need a second wrench to keep them from spinning. The full threading along the entire 4-inch length made installation a breeze with my impact driver.

Daniel F. ★★★★★

I needed a bunch for a pergola build and these fully threaded bolts made assembly a breeze since they don't spin while tightening. The square neck grabbed the wood perfectly right away.

Violet ★★★★★

The smooth rounded heads look clean once installed, and the full threading made seating them into the wood effortless. A full box of 750 is a solid deal for shop stock, though the plain steel finish means I’ll need to keep them dry.
