براغي رأس تجويف سداسية HOLO-KROME 72088 #10-24 X 2" | محرك تجويف سداسي | فولاذ سبائكي مع أكسيد أسود حراري (100 / عبوة)

All 100 screws came with clean threads and an even black oxide finish. The hex socket drive grips perfectly with no stripping, and they feel much harder than the cheap zinc ones I’ve used. These are going straight into my tooling setup.

The hex socket drive on these #10-24s bites perfectly with a standard Allen key—no stripping even when I torqued them down on my jig fixture. For a hundred pieces, the alloy steel feels plenty rigid for precision work.

Used six of these to repair a jig on my mill, and the hex drive seated perfectly without stripping. The black oxide coating seems consistent across all 100 screws, which is nice for a uniform look. Only wish the package included a few extras for the price.
