HOLO-KROME 720000090 براغي رأس مقبس #2-56 × 5/8" | محرك مقبس سداسي | سبيكة فولاذ أكسيد أسود حراري (50 / عبوة)

These little #2-56 screws are exactly what I needed for a jig build, the black oxide finish looks clean and should resist rust. They threaded smoothly into tapped holes without any binding.

The socket drive seated perfectly on my hex wrench, no stripping or wobble during assembly. The 5/8" length was exactly right for my jig setup, and all 50 pieces came out of the package with a clean, consistent black oxide coating.

The black oxide finish gave them that slightly grippy feel when seating with an Allen key, and they threaded cleanly into my precision fixture without any binding. I’ve got some serious torque on these little guys and not a single one has stripped.
