براغي رأس مقبس M12-1.75 × 65 مم | محرك سداسي برأس مسطح | ملولبة جزئيًا | فئة 12.9 من سبائك الصلب مطلية بالزنك (50 / عبوة)

Threaded all the way up to the head, these M12 bolts fit perfectly into a precision assembly I’m building, and the zinc coating looks clean. The hex drive engaged without any slipping, and the partial thread gave just the right grip for heavy loads.

Had to swap out some worn bolts on a jig fixture and these threaded in clean with zero binding. The partial thread gave just the right grip length for the assembly, and the zinc coating looks uniform across all 50 pieces.

The hex socket drive on these M12 screws fit my torque wrench perfectly, making installation on a jig quick and accurate. The zinc plating looks clean and should hold up well in the shop environment.
