براغي كاب مقبس HOLO-KROME 720000390 #6-32 × 5/16" | محرك مقبس سداسي | فولاذ سبائكي أكسيد أسود حراري (100/عبوة)

Used these to replace stripped screws on a milling machine fixture—the black oxide finish blends right in and the hex socket makes them easy to torque down without cam-out.

The black oxide finish on these screws gives them a nice, uniform look that blends in well on my equipment. They threaded smoothly into the pre-tapped holes on my jig without any binding.

These are exactly the right length for my jig, and the black oxide finish gives them a nice, uniform look against the alloy steel. The hex socket drive seated cleanly on my driver without any stripping, and all 100 in the package were consistent.
