HOLO-KROME 640010480 #6-32 × 7/8 بوصة مسامير رأس مقبس | رأس زر محرك سداسي | فولاذ سبائكي أكسيد أسود حراري (50/عبوة)

Installed these in a jig I’m building and the hex socket drive made them quick to tighten without stripping. The thermal black oxide coating feels tough and should hold up well in my shop.

The black oxide finish on these #6-32 screws looks clean and resists scratches well during assembly. They fit perfectly in my precision jig setup, and the hex socket drive gave me solid torque control without any stripping. Exactly what I needed for this tooling project.

Finally a button head screw that actually fits my jig properly without stripping. The black oxide finish is smooth and consistent across all 50 pieces.
