Customer Reviews (4.6 / 5 · 5 reviews)

Riley ★★★★★

I needed some bolts that would hold up in a damp garage, and these stainless ones with the unthreaded grip length fit perfectly through my brackets. No rust after a few weeks of exposure, and the hex head grabbed my socket wrench without slipping.

Mia ★★★★★

Grabbed these for a project where I needed precise alignment before the threads engaged, and the stainless finish feels solid and corrosion-proof. The partially threaded shank sits flush through the plate just as I hoped.

Ryan ★★★★★

I needed that unthreaded grip length for aligning metal parts, and these bolts fit perfectly through the holes without binding. The 18/8 stainless finish looks clean and should hold up well outdoors.
