HOLO-KROME 720002624 براغي مقبس 1/2-13 × 9" | محرك سداسي | فولاذ سبائك أسود حراري (10 / عبوة)

These 9-inch black oxide bolts fit my fixture plates perfectly, and the hex socket drive made torquing them down in tight spots a breeze. The alloy steel feels rock solid, I've got zero complaints after a week of heavy machining.

The thermal black oxide finish is evenly coated and hasn't chipped after a week of hammering these into a steel jig. The 9-inch length gives me plenty of thread engagement, and the socket drive is snug enough that they don't wobble under torque.

I needed long cap screws for a jig rebuild and these 1/2-13 x 9" ones fit perfectly. The black oxide finish looks clean and the hex socket drive made installation straightforward.
