Customer Reviews (4.6 / 5 · 5 reviews)

Daniel H. ★★★★★

Used a handful of these for a trailer hitch project and the zinc plating looks clean and hasn't shown any rust yet. The partial threading made it easy to get a solid grip without bottoming out.

Hazel R. ★★★★★

Packed these into a machinery baseplate and the partial threading grabbed perfectly without bottoming out. Grade B steel feels reassuringly solid, and the zinc coating looks like it'll hold up fine in a dry assembly shop.

Emma T. ★★★★★

The threads cut cleanly and the zinc coating looks durable. These worked perfectly for bolting down a heavy press in my shop.
