براغي رأس مقبس M6-1 × 120 مم | محرك سداسي | خيط جزئي | سبيكة فولاذ كلاس 12.9 مطلية بالزنك (100/عبوة)

The hex socket drive on these gives a much better grip than a standard hex head, which made installing them in a tight jig frame a breeze. The zinc plating has a nice uniform finish, and all 100 bolts threaded smoothly into the M6 tap without any binding. Perfect for my tooling project where consist

Needed some high-strength bolts for a custom jig I'm building, and these 12.9 alloy steel screws with the zinc plating fit the bill perfectly. The hex socket drive seated firmly with my wrench, and the partial threading gave just the right grip for my assembly.

Threaded almost the whole length like I needed for my jig setup, and the 12.9 grade steel feels seriously tough. These screws held up perfectly under high torque without stripping.
