Customer Reviews (4.8 / 5 · 5 reviews)

Emma ★★★★★

The black oxide finish on these screws really helps them hold up in a dirty shop environment without rusting. The 12.9 alloy steel feels incredibly sturdy, and the partial threading made aligning my jig fixture much easier than a fully threaded bolt would have.

Chloe F. ★★★★★

Used these for a heavy jig build and the Class 12.9 alloy steel held up perfectly under torque without any stretching. The partially threaded design made alignment in tight spots a lot easier than fully threaded caps I've tried before.

Samuel ★★★★★

The black oxide finish on these M20 bolts is holding up nicely in my fixture setup, and the hex socket drive made torquing them down a breeze. Used them to replace older hardware on a press tool, and the 12.9 alloy steel feels solid.
