براغي رأس كبس #5-44 × 7/8 بوصة | محرك سداسي | ملولبة بالكامل | فولاذ سبائكي مع أكسيد أسود حراري (200 / عبوة)

Just got these for a jig I'm building, and the hex sockets are cut cleanly enough that my driver seats without any wobble. Threads run smooth all the way down, and the thermal black oxide looks uniform across all 200 pieces.

The hex drive on these #5-44 screws fits my precision tooling perfectly, and the black oxide finish looks clean and professional. They hold tight without stripping when I torque them down, which is exactly what I needed for my jig setup.

I needed some small fasteners for a jig I was building, and these #5-44 screws fit perfectly in the hex socket driver I have. The fully threaded length is exactly what I needed for a secure hold in that tight assembly.
