براغي رأس مقبس سداسي M10-1.25 × 100 مم | محرك مقبس سداسي | ملولبة جزئيًا | فولاذ سبائكي فئة 12.9 مطلي بالزنك (50 / عبوة)

The threading is clean and the zinc coating looks uniform across all fifty, which is exactly what I needed for a tooling fixture. They torqued down smoothly into the tapped holes without any binding, and the 12.9 grade gives me real confidence in the hold.

Tried these on a jig I was building and the hex socket drive took my torque wrench perfectly. The zinc plating looks clean and hasn't shown any rust after a week of use.

The 12.9 rating is no joke—these bolts took a beating on my fixture without stripping or bending. Partially threaded design seated perfectly in my jig, and the zinc finish hasn’t shown a speck of rust after a humid week in the shop.
