HOLO-KROME 76480 براغي رأس مقبس M16-2 × 120 مم | محرك مقبس سداسي | فولاذ سبائكي أسود حراري (10/عبوة)

The threads on these M16 screws cut cleanly into the tapped hole without any binding, and the black oxide coating feels durable. Perfect for securing a heavy jig fixture on my mill.

Black oxide finish looks great and the threads cut cleanly into the steel plate I'm using them on. The hex socket drive grabbed firmly with my Allen key, no stripping at all even at full torque. Exactly the precision I needed for my tooling setup.

Installed these in a jig for a production run, and the black oxide finish held up perfectly against minor spills. The hex socket drive gives you a solid grip without stripping.
