براغي رأس أسطوانية M12-1.75 × 50 مم | محرك سداسي برأس زرية | ملولبة بالكامل | فولاذ سبائكي فئة 12.9 مطلي بالزنك (100 / عبوة)

I was worried about finding fasteners tough enough for jig building, but these fully threaded M12s handled the torque without any issue. The zinc plating looks clean and should resist rust well in my shop. Solid purchase for the price.

The hex socket drive on these made installation a breeze with my Allen key set, and the zinc coating gives them a nice smooth finish. Used them to secure a jig on my mill and they’ve held up under heavy vibration without any loosening.

These M12 cap screws fit perfectly for the jig I’m building, and the hex socket drive made tightening them a breeze. The zinc plating seems solid and clean, no rough edges at all.
