Avery ★★★★★

I needed some bolts with a precise unthreaded grip section for a custom bracket, and the partially threaded shank on these was exactly what I was looking for. The 18/8 stainless finish has held up perfectly so far, even in a slightly damp garage.

Charlotte W. ★★★★★

Threads were clean and the 18/8 stainless has a nice heft to it. I was pleasantly surprised the unthreaded grip section let me seat a bracket flush without any wobble, and all 50 arrived without a single burr.

George ★★★★★

The partially threaded shank is exactly what I needed for a clevis pin setup—that unthreaded grip section keeps everything tight without slop. These stainless bolts are a solid upgrade over the zinc ones I had before, and the 5/16-24 threads cut clean.
