براغي ذات رأس مقبس M14-2 × 45 مم | محرك سداسي | ملولبة بالكامل | فولاذ سبائكي فئة 12.9 مطلي بالزنك (50 / عبوة)

These went into a tooling fixture without any resistance, and the hex socket drive held the driver securely without stripping. The 45mm length is perfect for the heavy-duty brackets I'm assembling.

Installing these in a precision jig, I was impressed by how snugly the hex socket fit the driver – no wobble or stripping. The zinc plating looks clean and uniform across all fifty, and the class 12.9 rating gives me confidence they’ll hold tight under heavy loads.

Used these for a custom tooling fixture and the hex socket drive made installation so much easier than standard hex bolts. The zinc plating has a nice, uniform finish too.
