براغي ضبط رأس مقبس نقطة كوب M8 × 10 مم | فولاذ سبائكي مطلي بالزنك (500 / عبوة)

The hex socket drive made installing these into a tight motor mount a breeze without stripping. The cup point bites into the shaft securely, and the zinc plating seems durable for occasional moisture exposure.

Installed these on a pulley flange that kept slipping with standard grub screws and the hex socket drive made torquing them down easy even with the limited clearance. The cup point dug in firmly on the first tightening. Definitely a solid upgrade for any medium-duty shaft locking application.

The cup point really bites into the metal shaft, no slipping at all once torqued down. A full 500-count pack gives me plenty for multiple projects.
