براغي تثبيت ذات مقبس بنقطة كوب M12 × 15 مم | فولاذ سبائكي مطلي بالزنك (250/عبوة)

The cup point grips really securely on the shaft, and the zinc plating looks consistent across all 250 pieces. I used these for a jig build and they haven't budged under vibration.

I was pleasantly surprised by the hex socket drive on these—even in a cramped corner of the frame, I could get a wrench in without stripping anything. The zinc plating looks even and hasn't flaked after a week of assembly, which is more than I can say for other sets I've tried.

The cup point bites into the shaft firmly—no slipping even under heavy torque. Zinc plating looks uniform across all 250 pieces, and the hex socket drove cleanly in a cramped gearbox housing. Fast shipping, solid hardware for the price.
