براغي رأس كبس #5-40 × 3/4 بوصة | محرك سداسي | رقعة نايلون | خيط كامل | فولاذ سبائكي مؤكسد أسود حراري (300 / عبوة)

I’ve got a jig that’s been a pain to keep aligned, and these threaded in with no binding thanks to that nylon patch. The black oxide finish looks tough and hasn’t shown a hint of rust after a week of shop use. Pack of 300 means I’m set for a while.

The hex socket drive grips the Allen key perfectly, no stripping or wobble when I torqued them down on my jig. All 300 arrived with the nylon patch intact and the black oxide looks sharp against the steel fixture.

The thermal black oxide finish on these #5-40 screws gives them a nice, consistent look that resists wear in my jig setups. They fit the hex socket perfectly without any wobble, and the 300-count box should last me through several projects.
