براغي HOLO-KROME 72202 7/16-14 × 2 بوصة بمقبس سداسي | محرك مقبس سداسي | فولاذ سبائكي مؤكسد حراريًا أسود (50 / عبوة)

Used these on a jig I’m building and the 7/16-14 threads seated cleanly in the tapped holes without any binding. The thermal black oxide coating held up fine under a bit of wrenching—no flaking or rust spots after a couple days on the bench.

Perfect fit on my milling machine's T-nuts—the black oxide finish is holding up well. Threads were clean and started smoothly in all 50 pieces.

Machined some jig plates today and these black oxide screws seated perfectly with zero galling. The socket drive takes an Allen key cleanly, and all fifty of them came with threads that were consistent, no chips or burrs anywhere.
