HOLO-KROME 76204 M6-1 × 60 مم براغي رأس مقبس | محرك سداسي | فولاذ سبائكي أسود حراري (100/عبوة)

The black oxide finish on these M6 screws is what sold me—they slide into hex sockets cleanly without any binding. I’ve used about forty so far on a precision assembly rig and not a single stripped head or burr. This 100-pack is a solid value for shop stock.

Picked up a pack for a jig I was building, and the black oxide finish looks professional while resisting wear. The hex socket drive gripped perfectly with no stripping, and the 60mm length was spot on for my assembly.

Used a handful of these M6 screws to replace some stripped fasteners on my lathe, and the black oxide finish is holding up beautifully against cutting oil. The threads engage smoothly without any binding, which saves time during assembly.
