M3-0.5 x 8mm 육각 머리 볼트 | 클래스 8.8 강철 아연 도금 | 풀 스레드 (500개/팩)

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.

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

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.
