Customer Reviews (4.4 / 5 · 5 reviews)

Miles S. ★★★★★

I needed these for a jig repair and the partially threaded design grabbed perfectly where a full thread would have stripped. The black oxide finish seems tough enough to handle regular shop use without rusting.

Hannah ★★★★★

The hex socket drive made installation really smooth, and the black oxide finish looks great on my tooling jig. These feel solid and well-machined, exactly what I needed for a precision assembly.

Benjamin I. ★★★★★

Installed these on a heavy-duty fixture I’m building, and the hex socket drive made tightening them in tight spots a lot easier. The black oxide finish seems durable and hasn’t marred during assembly.
