براغي رأس مقبس M8-1.25 × 70 مم | رأس زر محرك مقبس سداسي | كاملة الخيوط | فولاذ سبيكة كلاس 12.9 مطلي بالزنك (100 / عبوة)

Put these on a custom jig I built for a small production run, and the 12.9 grade steel really holds up under torque without stripping. The hex socket drive seated nicely with my Allen key, and the zinc coating has a clean, even look.

I needed longer bolts for a jig I was building and the 70mm length on these worked perfectly. The hex drive seated cleanly and the zinc coating on the alloy steel looks consistent across all 100 pieces.

Zinc plating looks even and consistent across all 100 pieces, which is what I was hoping for when I ordered them for my jig setup. The hex socket drive bites cleanly without stripping, though the 70mm length means you’ll want a deep socket for tightening.
