براغي رأس سداسي M12-1.75 × 50 مم | فولاذ فئة 8.8 مطلي بالزنك الأصفر | ملولب بالكامل (100/عبوة)

Used these on a heavy equipment repair job, and the yellow zinc held up fine with no rust after a week of rain. The hex head gave a solid bite with my socket, no rounding. Good value for a full box.

Perfect fit on my milling machine’s hold-down clamps, and the hex head grabs a socket securely without stripping. The yellow zinc coating looks consistent and should resist rust around coolant.

Used these to bolt down a new workbench frame and the hex heads were easy to drive with a socket. All 100 threads were clean and consistent, so every bolt started smoothly without binding. Solid value for the price.
