HOLO-KROME 61010 #10-32 × 1" براغي رأس أسطواني | رأس مسطح محرك سداسي | فولاذ سبائكي أسود حراري (100/عبوة)

The black oxide finish on these #10-32 screws has held up perfectly during my jig assembly work, no chipping or rust. They fit snugly into the hex socket and threaded holes without binding. Exactly what I needed for precision tooling.

Loosely installing a few of these #10-32 screws confirmed the black oxide finish rubs off less than cheaper fasteners I've used, and they seated flush in my jig plate without stripping.

The socket drive gripped perfectly, no stripping even when I torqued them into my jig fixture. All 100 in the package came out clean and true, and the black oxide coating gives them a solid, professional look under the shop lights.
