HOLO-KROME 60012 #5-40 X 1/4" براغي ذات رأس أسطواني | رأس مسطح محرك سداسي داخلي | سبائك فولاذية مؤكسدة حرارياً باللون الأسود (100 / عبوة)

The black oxide finish on these is a nice touch—they seat flush in the counterbores without any snagging. Threads cut cleanly into the tapped holes, and the hex drive bites well, so I didn’t strip a single one across the whole pack of 100.

Used these on a jig build today and the black oxide finish is nicely uniform across all 100 pieces. The #5-40 threads cut clean and the flat heads seated without any wobble.

The black oxide finish is nice and even, no flaking when I ran a nut down the threads. They seated flush in my jig plate without any wobble, and the hex drive gripped firmly on the first try.
