براغي رأس كبس M10-1.5 × 22 مم | محرك سداسي | ملولبة بالكامل | فئة 12.9 من سبائك الصلب مطلية بالزنك (100/عبوة)

Installed these on a motorcycle engine mount and the 12.9 alloy steel held up perfectly under heavy torque. The zinc plating on all 100 screws looks clean and even, no chipping.

Used these for building a custom jig and the Class 12.9 alloy steel feels noticeably stronger than standard hardware. The zinc plating looks clean and consistent across all 100 pieces.

The hex socket drive on these screws made installation a breeze with my Allen wrench, and the 22mm length was perfect for securing a metal bracket that needed a clean, flush finish. They fit snugly without any wobble, which is exactly what I needed for this precision assembly.
