HOLO-KROME 32252 براغي تثبيت ذات رأس مقبس بنقطة كوب 5/8-11 × 2-1/2 بوصة | فولاذ سبائكي مع طلاء أكسيد أسود حراري (10 / عبوة)

The cup point bit right into the shaft with no slipping when I torqued it down, and the black oxide finish seems durable for shop use. Tapped cleanly into a 5/8-11 hole I'd prepped, and all ten screws had consistent threads.

I needed these for a shaft-mounted gear repair, and the black oxide finish made them slide into the tapped hole with zero galling. The hex drive seated firmly without stripping, and the cup point held tight after a few turns—just what I needed for a solid clamp.

The cup point bit into the shaft exactly where I needed it, and the hex drive seated cleanly without stripping. These 5/8-11s held firm under load, and the thermal black oxide gave them a nice consistent finish that didn't flake off during install.
