Customer Reviews (5.0 / 5 · 5 reviews)

Owen ★★★★★

I needed fasteners that wouldn't strip under torque, and these fully threaded M3 bolts held perfectly when I tightened them with a hex key. The zinc plating gives them a clean, consistent finish, too.

Alexander ★★★★★

The hex heads sit flush in my wrench without any wobble, and the zinc coating gives them a clean, uniform finish. I've used about half the bag on a gearbox rebuild and not a single one has stripped during torquing. Class 8.8 feels solidly overkill for what I needed, but that's a good problem to have

Scarlett ★★★★★

Had to replace some stripped screws on a CNC jig, and these M3-0.5 x 8mm hex heads were a perfect fit. The class 8.8 steel feels solid, and the hex drive made tightening them down with a socket a breeze.
