براغي رأس كبس H6-32 × 7/16 بوصة من هولو-كروم 720000410 | محرك سداسي | فولاد سبائكي مع أكسيد أسود حراري (100/عبوة)

I needed these for a jig I’m building, and the hex socket drive makes installation much easier than a slotted screw. The alloy steel feels sturdy, and the black oxide finish looks clean.

Threads are clean and uniform across the whole pack, and the black oxide finish gives them a nice, consistent grip in my wrench. They seated perfectly into my fixture without any binding or wobble, which is exactly what I hoped for from a precision assembly.
