براغي رأس مقبس من HOLO-KROME 72072 #10-24 X 1/2 بوصة | محرك سداسي المقبس | فولاذ سبائكي مؤكسد أسود حراري (100 / عبوة)

Put these on a small indexing fixture I'm assembling and the black oxide finish gives them a nice look while resisting scratches during adjustment. The hex socket drive makes them easy to tighten with a standard Allen key, even in tight spots.

For a precision jig I'm building, the hex drive seated perfectly without any cam-out, and the threads were consistent across all 100 screws. Exactly the quality I needed for repeat adjustments.

Used a handful of these to secure a jig on my drill press, and the hex socket drive made installation effortless with no stripping. The black oxide finish looks durable and professional, and every screw threaded in perfectly.
