براغي رأس مقبس M12-1.5 × 35 مم | محرك مقبس سداسي | ملولبة بالكامل | فولاذ سبيكة فئة 12.9 أكسيد أسود حراري (100/عبوة)

The black oxide finish on these socket cap screws looks professional and seems durable. Used a dozen on a fixture build and every one threaded smoothly with no binding. Good hardware for the price, will reorder for future projects.

These fasteners fit perfectly into a jig I’m building, and the hex drive took the torque without stripping. The black oxide coating looks good and should resist minor corrosion.

Was pleasantly surprised by the finish on these screws—the black oxide coating has a nice, uniform look that resists fingerprints well. Used a few to secure some heavy jig fixtures and the 12.9 alloy steel definitely feels tougher than the standard 10.9 stuff I've used before.
