براغي رأس أسطواني مقاس M10-1.25 × 75 مم | محرك سداسي | ملولبة جزئيًا | فولاذ سبائكي فئة 12.9 مطلي بالزنك (50 / عبوة)

The partially threaded design made installation into my jig much easier than fully threaded bolts would have. These M10s fit perfectly and the hex drive seated firmly without any stripping.

Used these for a tooling fixture on a milling machine, and the 12.9 grade held torque perfectly without stripping. Threads were clean and the zinc coating looks like it'll resist rust well.

Installed these in a jig I'm building and the hex socket drive took torque without stripping. The zinc plating looks uniform and the partial threads seated cleanly. Exactly what I needed for precision assemblies.
