براغي تجويف سداسية برأس كوب M10 X 12mm | فولاد سبائكي مطلي بالزنك (250 / عبوة)

I was a little worried about stripping the hex socket on such small set screws, but the cup point bit in firmly without any issues. The zinc plating looks solid and they threaded cleanly into the pre-drilled holes.

The hex socket drive made cinching these down in a cramped gearbox surprisingly easy, and the cup point bit in firmly without stripping. All 250 arrived clean and evenly plated, zero duds in the batch.

Took a chance on these for a repair job and the cup point bites down hard, no slipping even with serious torque. Zinc plating looks uniform across all 250, not a single dud in the box.
