براغي رأس سداسي M12-1.75 × 180 مم | فولاذ فئة 10.9 مطلي بالزنك | ملولبة جزئيًا (25 / عبوة)

Picked up these M12-1.75 screws for a machine build, and the partial threading made alignment a breeze. The hex head fit my socket perfectly, and after tightening them down, they held solid with no issues.

Had to torque these down on a custom frame mount and the hex head gave the socket a solid grip without any slipping. The zinc coating seems consistent and should hold up fine in a dry workshop.

Installed these on a heavy press jig and the partial threading made alignment much easier than a fully threaded bolt would have. All 25 pieces had consistent zinc coating with no burrs on the threads.
