HOLO-KROME 64024 #8-32 × 3/4 بوصة براغي مقبس | رأس زر محرك سداسي | فولاذ سبائك أكسيد أسود حراري (100 / عبوة)

Grabbed a box for a jig I’ve been building and the hex socket drive seated perfectly with my Allen key—no stripping even on the first few tightenings. The black oxide finish looks tough, and at 3/4” length they’re just right for the precision assembly work I do.

The black oxide coating on these screws gives them a nice, uniform finish that blends well with dark tooling components. I used them for a precision fixture and was pleased that all 100 pieces had clean, well-formed threads without any burrs.

The hex socket drive made installing these into tight spaces on my jig a breeze. They fit perfectly in the pre-tapped holes, and the black oxide finish seems durable so far.
