براغي رأس مقبس M6-1 × 14 مم | محرك سداسي | ملولبة بالكامل | فئة 12.9 فولاذ سبائكي مؤكسد أسود حراريًا (600 / عبوة)

The black oxide finish on these screws is holding up beautifully in my jig setup, no signs of wear after repeated adjustments. The hexagonal drive bites perfectly without any cam-out, and having a full 600-count package means I won't run out mid-project.

Installing these on a jig fixture and they threaded cleanly into tapped holes without any binding. The black oxide finish looks consistent across all 600 pieces, and the hex socket drive made them easy to torque down in tight spots.

These M6 screws feel incredibly solid when tightening—the hex socket drive grips perfectly without any stripping. For the price of a 600-pack, they're an unbeatable deal for jigs and fixture work.
