براغي رأس مقبس M24-3 X 170mm | محرك سداسي | ملولبة جزئياً | فئة 12.9 سبائك فولاذية مؤكسدة حرارياً باللون الأسود (10/عبوة)

Tightened down several M24 socket caps on a jig fixture this morning and the hex socket drive seated perfectly without any stripping. Threads cut clean and the thermal black oxide layer looks uniform across all ten pieces, which is exactly what I need for long-term corrosion resistance on the shop f

The black oxide finish on these M24 screws looks professional and held up well during assembly. The hex socket drive made installation straightforward, and they fit perfectly into my jig setup.

The threads cut cleanly on my lathe without any binding, and the 12.9 alloy steel feels plenty rigid for the jig frame I'm bolting together. The partial threading gave me just the right grip length for a 70mm spacer stack.
