براغي رأس كبس M8-1.25 × 12 مم | محرك سداسي | خيط كامل | فئة 12.9 سبيكة فولاذ مطلية بالزنك (200/عبوة)

The zinc plating is holding up nicely after a week on my milling fixture, no rust or marring yet. The 12.9 alloy steel feels genuinely tough when torquing them down with the hex wrench, and the full threading makes seating them in tight spots quick. Exactly what I needed for tooling work.

The hex socket drive on these M8 screws grabbed my Allen key perfectly, making assembly on my jig much smoother than with the cheaper bolts I'd used before. The class 12.9 alloy steel feels solidly over-engineered for what I'm doing, and the zinc plating looks clean out of the bag.

I used these for a small precision assembly project, and the fully threaded design with hex socket made installation quick and clean. The zinc plating looks consistent across all 200 pieces.
