براغي رأس مقبس M6-1 × 12 مم | رأس منخفض بمقبس سداسي | ملولبة بالكامل | فولاذ سبائكي فئة 10.9 مؤكسد أسود حراريًا (200/عبوة)

The hex socket drive made installation in my jig's tight spots effortless, and the black oxide finish looks clean and corrosion-resistant. I used these to secure a custom bracket and didn't strip a single head—the alloy steel feels solid.

Installed these M6-1 x 12mm screws in a jig I was building for a milling machine, and the Class 10.9 steel held torque perfectly without stripping. The black oxide finish handled the oily shop environment well with no corrosion after a week of use. Exactly what I needed for precision fixturing.

Installed these in a jig last week and the low head profile was perfect for tight clearances. All 200 came with clean threads and consistent depth, no duds in the batch.
