Customer Reviews (4.4 / 5 · 5 reviews)

Natalie ★★★★★

I’ve been using these in a few precision assemblies, and the Class 12.9 alloy steel feels noticeably tougher than standard bolts. The hex socket drive fits snugly with no rounding, and the thermal black oxide finish looks clean.

Eva S. ★★★★★

The partially threaded design made setting up my jig a lot easier than dealing with fully threaded bolts. The black oxide finish feels properly tough, and all 25 pieces looked clean with no burs out of the package.

Chloe ★★★★★

The partial threads on these M20s make seating them in jigs so much easier than fully threaded bolts, and the black oxide finish looks sharp. Torqued a few into a tooling plate today and they held perfectly without a hint of stripping. Exactly what I needed for heavy machinery work.
