براغي رأس أسطوانية M10-1.25 X 16mm | محرك سداسي | ملولبة بالكامل | فئة 12.9 فولاذ سبائكي مطلي بالزنك (100 / عبوة)

Used these for a precision assembly at work and the hex socket drive held torque perfectly without stripping. The Class 12.9 alloy steel feels noticeably tougher than standard bolts.

Installed these on a jig I built for drilling alignment holes, and the hex socket drove in smooth without stripping. The 12.9 alloy steel feels tougher than the standard bolts I've used before, and the zinc plating looks clean.

These came in a plain bag but the threading is clean and the hex sockets seated my Allen key perfectly with zero play. Used a dozen on a jig build and the zinc finish looks consistent across the whole lot.
