براغي رأس كبسولة H0L0-KR0ME 64042 1/4-20 × 1/2 بوصة | محرك سداسي رأس زر | فولاد سبيكي مؤكسد أسود حراري (100 / عبوة)

The black oxide finish on these screws looks clean and resists scratching during assembly. Used a bunch to mount some jig fixtures and every one threaded smoothly without binding. A solid buy for anyone doing precision tooling work.

The hex drive fits my socket wrench perfectly—no stripping like with Phillips-head bolts. Used a dozen already on a jig I'm building and they threaded in smooth. Solid little fasteners for the price.

The black oxide finish is holding up perfectly on the machining fixtures I assembled, and the hex socket drive makes them easy to seat without stripping. I ordered the 100-pack and every single screw threaded cleanly into tapped holes—no duds, no hesitation.
