Customer Reviews (4.8 / 5 · 5 reviews)

Charlotte L. ★★★★★

I used these for a custom jig build and the 12.9 grade steel felt noticeably tougher than standard bolts. The black oxide finish held up well against light moisture during assembly. Good value for a hundred-piece lot.

Zoe I. ★★★★★

The hex socket drive grips the allen key perfectly with zero wobble, and the black oxide finish looks sharp on my tooling fixtures. Threads ran smooth all the way through the tapped holes, and the 12.9 hardness gives me real confidence in these under load.

Victoria O. ★★★★★

I needed these for a jig I'm building, and the hex socket drive made installation way smoother than using a standard hex key. The 12.9 alloy steel feels reassuringly hard, and the black oxide finish looks uniform across all 100 pieces.
