براغي ذات رأس مقبس منخفض 5/16-24 × 1/2 بوصة | محرك سداسي | فولاذ سبائكي أسود حراري (100 / عبوة)

Needed some exact-fit low head screws for a tight clearance on a tooling fixture, and these black oxide ones worked perfectly. The hex socket drive made installation straightforward, and all 100 in the pack had clean threads. Exactly what I needed for precision work.

I was worried about finding the right fasteners for a tooling jig I'm building, but these low head screws fit perfectly in the tight space and the alloy steel feels really solid. The hex socket drove in cleanly without any stripping, and the black oxide finish looks professional.

Picked up a pack for some jig work I've been putting off. The black oxide finish looks clean and the hex drive seated nicely on the first try. Only wish the package had a few extras for the price.
