براغي رأس مقبس M6-1 × 115 مم | محرك مقبس سداسي | ملولبة جزئيًا | سبيكة فولاذ درجة 12.9 أكسيد أسود حراري (100 / عبوة)

These M6-1 x 115mm screws cut clean threads in my steel jig plate without stripping. The partial threading gave me just the right grip depth for a secure hold in a tight assembly. I’ve had zero issues with them, and the black oxide finish has held up nicely against oil and grime.

The black oxide finish on these screws is a nice touch for a clean look in my jig builds, and the 12.9 grade gives me confidence they won't snap under load. Threaded section is just right for clamping down tight.

Finally, a 115mm length that actually fits my jig setup without any wobble. The black oxide finish feels tough and the hex socket drive made installation straightforward.
