براغي رأس مقبس M12-1.75 × 160 مم | محرك مقبس سداسي | ملولبة جزئيًا | فولاذ سبائكي فئة 12.9 مؤكسد أسود حراريًا (20 / عبوة)

Used these to secure a heavy-duty jig on a milling table and the partially threaded design held tight under vibration. The black oxide finish looks professional and seems durable. Exactly what I needed for precision assemblies.

The 160mm length is spot-on for the tooling fixture I needed, and the hex socket drive made installation effortless with a basic Allen key. These feel incredibly robust, definitely a solid upgrade from the standard bolts I was using before.

I was installing these in a jig setup and the hex socket drive held the allen key firmly without stripping. The thermal black oxide finish seems durable and looks clean in the assembly. Only wish the package included a couple extras for the price.
