HOLO-KROME 32274 براغي تثبيت ذات رأس مقبس بنقطة كوب 7/8-9 × 7/8" | سبيكة فولاذية بأكسيد أسود حراري (10 / عبوة)

The hex socket drive made installation straightforward with a standard Allen key, and the black oxide finish looks clean against the metal shaft. I used these to secure a pulley on a lathe and they haven't budged under heavy load.

The black oxide coating on these screws looks great and seems like it will resist rust well. The hex socket drive made them easy to install in a tight spot on my shaft project. Exactly the cup point design I needed for clamping.

The hex socket drive seated the Allen key firmly with no wobble, and the cup point bit into the shaft exactly where I marked it. Black oxide finish looks consistent across all ten pieces, though I wish the package included a few spares for the price.
