براغي رأس سداسي M12-1.5 × 35 مم | فولاذ فئة 10.9 مطلي بالزنك | ملولبة بالكامل (100/عبوة)

These grabbed perfectly with my impact driver on a steel frame I was bolting together. The 10.9 hardness is no joke, and I didn't strip a single head across the whole bag of 100.

The zinc plating looks uniform across all 100 pieces, and the hex heads held up perfectly under a breaker bar without stripping. These fully threaded M12s torqued down clean on our press fixture, no burs or dodgy threads in the batch.

Needed some class 10.9 bolts for a frame repair and these hex heads took a socket easily without stripping. The zinc plating looks clean and should resist rust just fine.
