HOLO-KROME 32108 براغي ضبط رأس كوبية #10-24 X 1" | سبائك الصلب أكسيد أسود حراري (100 / عبوة)

The hex socket drive grabbed my Allen key cleanly on every single screw, and the cup point bites into the shaft without slipping. I’ve got 100 of them now, so I won’t run out mid-project.

I’ve used a few packs of these #10-24 set screws for clamping pulleys on shafts and the cup point bites down securely without stripping, even after repeated adjustments. The thermal black oxide finish looks clean and hasn’t rusted in my damp garage.

The hex socket drive made installation effortless, and the black oxide finish adds a nice touch of durability. These cup point screws sit flush perfectly for clamping components in tight spots.
