HOLO-KROME 69516 براغي رأس مقبس M10-1.5 X 30 مم | محرك مقبس سداسي منخفض الرأس | فولاذ سبائك أكسيد أسود حراري (100/عبوة)

Put a set of these on a custom jig I’ve been building, and the black oxide coating gave them a nice, even finish with no burrs. Threaded smoothly into tapped holes without binding, which made assembly a lot faster than I expected.

The thermal black oxide finish on these screws is darker and more uniform than cheap zinc-plated ones I've used, and the low head profile fits perfectly in tight jig spots. The 100-count box means I don't have to reorder mid-project.

I’ve gone through a few packs of these for jig builds and the low head profile is a lifesaver where clearance is tight. The black oxide finish has held up well so far with no rust spots after sitting in a damp shop. A full box of 100 means I won’t be reordering for a while.
