HOLO-KROME 76026 براغي رأس مقبس M3-0.5 × 15 مم | محرك سداسي | سبيكة فولاذ أكسيد أسود حراري (100 / عبوة)

I was a little worried about stripping the hex drive on such small screws, but these seated cleanly into my precision fixture without any fuss. The black oxide finish looks consistent across all 100 pieces, and the M3 threading feels precise all the way in.

Pulled these out for a small jig build and the hex drive seated perfectly without any stripping. The black oxide finish seems consistent across all 100 pieces, which is a nice change from cheaper packs.

Finally, a batch of M3 screws where every single one threads smoothly without any burrs. The black oxide finish looks great on my CNC jig, and the 100-count pack means I won't run out mid-project.
