Customer Reviews (4.8 / 5 · 5 reviews)

Ellie B. ★★★★★

Installed these on a custom jig for a milling fixture I'm building, and the hex socket drive made tightening them a breeze. The 12.9 alloy steel feels noticeably sturdier than standard 10.9s. Only wish the 20mm length came with a slightly taller head, but they fit the counterbored holes perfectly.

Henry G. ★★★★★

The black oxide finish looks properly done—no patchy spots, and they threaded into my tooling plates without any binding. For the price of a hundred, these class 12.9s are a solid deal for precision assemblies.

Riley E. ★★★★★

Installed these in a jig I’m building, and the black oxide finish held up to clamping pressure without any flaking. The hex socket drive made seating them in tight spots much easier than a standard allen bolt.
