HOLO-KROME 72304 براغي ذات رأس مقبس 3/4-10 × 1-1/2 بوصة | محرك مقبس سداسي | فولاذ سبائكي أسود حراري (25 / عبوة)

Needed a strong fastener for a jig rebuild and these alloy steel screws handled the torque without any stripping. The black oxide finish is a nice touch for shop use, keeps them looking clean longer than plain steel.

Took these to the shop for building a new fixture, and the hex socket drive grabbed beautifully without any stripping. The alloy steel feels solid and the threads were clean right out of the box.

The black oxide finish made these screws slide into the jig without binding, which was a relief. I used half the pack on a tooling fixture, and they torqued down solidly without stripping. Just wish the threads were a hair cleaner out of the bag.
