HOLO-KROME 32236 براغي تثبيت مقبس بنقطة كوب 5/8-11 × 1/2" | فولاد سبائك بأكسيد أسود حراري (100 / عبوة)

The black oxide finish on these cup point screws looks clean and professional once seated. I used them to secure a pulley on a shaft, and the hex drive held tight without stripping. A solid, no-nonsense hardware pack for any shop.

I needed some heavy-duty set screws for a stubborn shaft collar, and the hex socket drive on these made installation a breeze with no stripping. The black oxide finish looks clean and should resist rust well in my machine shop environment.

These cup point set screws bite into the shaft securely once you get them snugged down with a hex key. The black oxide finish seems durable and should resist rust well on my machine tooling setups.
