HOLO-KROME 76605 براغي رأس أسطوانية M2-0.4 × 5 مم | محرك سداسي | فولاذ سبائكي مؤكسد حراري أسود (100 / عبوة)

The black oxide finish on these M2 screws holds up well even in my oily workshop environment, and the hex drive lets me torque them down precisely without stripping the tiny heads. They fit perfectly into my jig assembly for small CNC fixtures.

I’ve been using these for mounting small jigs, and the M2-0.4 thread engagement feels precise and snug. The thermal black oxide coating holds up well against light wear in my shop.

The black oxide finish really locks in nicely on my jig fixtures, no rust after weeks of use. They thread cleanly without binding, even into tight blind holes.
