HOLO-KROME 72040 براغي رأس أسطوانية مقاس #6-32 × 3/8 بوصة | محرك سداسي | فولاذ سبائكي بأكسيد أسود حراري (100 / عبوة)

The black oxide finish on these screws looks clean and uniform, and the alloy steel feels solid when I'm torquing them into my jig. All 100 came in the package with no damaged threads, which is exactly what I want for precision assemblies.

The hex socket drive fits my driver bit perfectly, zero wobble, and the #6-32 threads cut clean into my aluminum jig. Thermal black oxide finish hasn't flaked after a week of assembly and disassembly, so these will be a staple in my shop.

The black oxide finish on these screws looks professional and the hex drive makes them easy to tighten without stripping. They fit perfectly into my jig setup for a precision assembly project.
