HOLO-KROME 72266 5/8-11 X 1-1/4" براغي ذات رأس مقبس | محرك سداسي | سبائك فولاذية مؤكسدة حرارياً باللون الأسود (25 / عبوة)

I’ve been using these for jig assembly, and the alloy steel feels solid under torque. The hex socket drive engaged cleanly without any stripping during tightening.

The black oxide finish on these screws is perfect for tooling fixtures where I don’t want any reflection, and the socket drive seats a hex key without any wobble. Each of the 25 in the pack came out of the box with clean, sharp threads that started by hand.

I’ve been using these socket cap screws for a few days now in a custom jig I’m building, and the black oxide finish seems like it’ll hold up well against wear. The hex drive seated cleanly without stripping when I torqued them down.
