براغي رأس مقبس M2-0.4 × 12 مم | محرك مقبس سداسي | ملولبة بالكامل | فئة 12.9 سبيكة فولاذ مطلي بالزنك (600 / عبوة)

Just installed these on a jig I'm building and the hex socket drive made tightening them in tight spots so much easier. The zinc plating looks clean and the threading engaged smoothly right out of the box.

Used them for a small precision assembly project and the hex socket drive made installation a breeze. The zinc plating also seems durable and corrosion-resistant. Exactly what I needed for reliable fastening in tight spaces.

Installing these into a jig fixture was effortless—the 12.9 alloy steel feels incredibly robust for such a small screw. The zinc plating looks consistent across all 600 pieces, so I expect good corrosion resistance over time.
