Customer Reviews (5.0 / 5 · 5 reviews)

Julian L. ★★★★★

The hex socket drive made tightening these into a jig much easier than using a regular bolt. They held up well during assembly without any stripping, and the partial threading gave a clean fit.

Aurora ★★★★★

Finally, a partially threaded bolt long enough for my jig build without having to stack washers. The 18/8 stainless finish looks clean and the threads cut smoothly into my fixture plate.

Ava ★★★★★

The hex socket drive grabbed my Allen key perfectly with zero stripping, even after torquing them down hard on a fixture. These partially threaded M20s held everything rock solid for a week of heavy use, and the 18/8 stainless finish still looks clean.
