Customer Reviews (4.8 / 5 · 5 reviews)

Benjamin C. ★★★★★

The threading is perfectly clean and catches smoothly, and the zinc coating looks like it'll hold up well in a damp shop. These bolts are exactly what I needed for rebuilding a press stand.

Natalie B. ★★★★★

Installed these on a piece of heavy equipment and the zinc coating held up well against the initial wrenching, no galling. The full threading gave me plenty of bite in a deep nut.

Christopher T. ★★★★★

These threads cut clean and started easily with just a little oil, no binding halfway in. I’ve used cheaper imported bolts before, but these don’t strip the threads even after tightening down heavy equipment.
