براغي رأس كاب سوكيت M12-1.75 × 190 مم | محرك سداسي سوكيت | خيط جزئي | فئة 12.9 فولاذ سبائكي مع أكسيد أسود حراري (10 / عبوة)

I was replacing some worn jig bolts and these M12 black oxide cap screws threaded in smoothly with no binding. The partial threading let me seat them deep into the fixture plate without bottoming out. Perfect length for my tooling setup.

Finally a button head cap screw that is long enough for my jig fixtures; the 190mm length saves me from stacking washers. The black oxide finish looks clean and the hex socket drive holds up well under repeated torque.

These M12 black oxide bolts turned out perfect for the jig I'm building; the hex socket drive made installation quick and easy. The 190mm length was exactly what I needed for the thick clamping plates.
