HOLO-KROME 76216 براغي رأس مقبس M6-1 X 75mm | محرك سداسي | سبيكة فولاذية مؤكسدة حرارياً سوداء (100 / عبوة)

Threads bit cleanly into both my mill fixture and some 4140 blocks, no galling or stripped heads even with a 6mm allen key torqued down hard. The black oxide finish stayed intact across a dozen installs, and the 75mm length gave me just enough reach for my deeper jig builds.

Picked up a pack for some jig adjustments and the hex socket drive gripped perfectly without stripping. At 75mm length, they were exactly what I needed for those deeper clamping setups.

The black oxide finish on these M6 screws looks sharp and resists the usual rust spots I get in my shop. They seated cleanly into my precision fixture without any galling, and the alloy steel feels solid for the torque I applied. A solid hundred-count pack for this price is hard to beat.
