براغي رأس كبس مقبس M10-1.5 × 85 مم | رأس زر محرك مقبس سداسي | ملولب بالكامل | فولاذ سبائكي فئة 12.9 أكسيد أسود حراري (50 / عبوة)

I needed some strong bolts for a jig I was building, and these 12.9 grade screws were the perfect fit. The thermal black oxide coating has a nice, consistent finish that resisted scuffing during installation.

The hex socket drive seated perfectly on my torque wrench, and the 12.9 alloy steel threads cut cleanly into the jig plate without any wobble. I've already used half the pack on a machine frame and they're holding rock solid.

These arrived with a clean, even black oxide finish and the threads are cut perfectly—not a single one needed chasing before going into my fixture plates. The 12.9 alloy rating gives me confidence these will hold up where the cheap hardware kept snapping.
