8-BA × 1/4" براغي رأس مقبس | محرك سداسي | خيط كامل | فولاذ سبيكة أكسيد أسود حراري (200/عبوة)

These little screws are exactly what I needed for a jig I was building, and the black oxide coating looks sharp and seems tough. Out of the whole pack of 200, every single one threaded cleanly without any gunk or rough edges.

The hex socket drive grips the Allen key perfectly, no stripping even when I torqued them down on a fixture. The black oxide finish looks clean and they're all uniformly threaded straight out of the 200-pack.

Got a full box of 200 for a jig I’m building, and the thermal black oxide finish has a nice, even matte look that resists smudging. Threads are clean and seat without binding—solid value for precision work where you need a reliable grip every time.
