براغي ذات رأس مقبس HOLO-KROME 86006 M3-0.5 × 16mm | رأس زر محرك سداسي | فولاذ سبائكي أسود حراري (100/عبوة)

The black oxide finish on these M3 screws is really consistent and clean, and they fit perfectly into my precision assembly jigs. No stripped heads or misaligned threads in the whole pack.

I needed M3 screws for a jig at work and these fit perfectly with zero play in the threads. The hex socket drive made installation quick with no stripping.

Took these out of the bag and the threads are cut perfectly clean, no burrs at all. I've used them across three different jigs so far and every single one seated flush without needing to chase the holes. The black oxide feels evenly coated, so they should hold up fine in my shop.
