براغي رأس مقبس M8-1.25 × 80 مم | سداسي | ملولبة جزئيًا | فئة 12.9 سبيكة فولاذ أكسيد أسود حراري (100 / عبوة)

Exactly the right length for my jig table's hold-down clamps, and the partial threading lets me cinch down tight without bottoming out. The black oxide finish is a nice touch, and all 100 arrived clean with no burrs on the hex sockets.

Had to swap out a stripped bolt on my jig fixture and these threaded in clean with zero binding. The 12.9 alloy is reassuringly stiff, and the black oxide finish is even and consistent across all 100 pieces.

The black oxide finish on these M8 screws gives them a nice, professional look for jig building. The hex socket drive made installation with a standard allen key very straightforward, and the partial threading helped with alignment.
