Leo ★★★★★

These were a perfect fit for mounting a heavy motor mount on my bench; the partially threaded shank gave me just the right grip length without binding. The zinc coating looks clean and should hold up well in my garage.

Thomas S. ★★★★★

Installed these on a jig I was building, and the unthreaded grip length kept everything aligned perfectly — no slop in the joints. The zinc coating on every bolt looks uniform, no bare spots that would rust in my shop.

Brian ★★★★★

Picked up a pack for a shelving project I'm working on in the garage, and the partially threaded shank is exactly what I needed for a clean, snug fit through the uprights. They threaded smoothly into my pre-tapped holes without any binding.
