Customer Reviews (4.8 / 5 · 5 reviews)

Hannah ★★★★★

I used these to secure the base plate on a press jig, and the partially threaded shank let me get a clean clamp without bottoming out. The black oxide finish also seems tough enough to resist the shop grime.

Grace ★★★★★

The hex socket drive grips the allen key without any slip, even when I torqued these down on a jig fixture. The black oxide finish also held up well against light shop grime. Exactly what I needed for the precision assembly.

Alexander Y. ★★★★★

The partially threaded shank made aligning these in a tight fixture much easier than expected, and the black oxide finish looks professional. I’ve already ordered another set for a different project.
