HOLO-KROME 32068 براغي مقبس سداسي بنقطة كوب #6-32 × 1 بوصة | فولاذ سبائكي بأكسيد أسود حراري (100/عبوة)

The cup point grips the shaft securely without slipping, and the black oxide finish looks clean and resists rust. Threaded smoothly into the tapped hole on my first try.

The hex socket drive made installation so easy with my Allen key, and the cup point bit into the shaft exactly where I needed it to hold a gear in place. All 100 came clean, no burrs, and they threaded smoothly into tapped holes right out of the package.

These set screws held tight on a small pulley shaft I installed last week, no slipping at all. The cup point really bites into the metal—exactly what I needed for a permanent mechanical lock.
