HOLO-KROME 60142 5/8-11 X 1-1/4" براغي قبعة مقبس | رأس مسطح بمحرك مقبس سداسي | فولاذ سبائكي بأكسيد أسود حراري (25/عبوة)

Used a few in a custom fixture build and the flat head seated perfectly flush, no issues stripping with the hex drive. The black oxide coating held up well during tightening—solid feel throughout.

The hex socket drive made installation really easy with my allen wrench, and the flat head sits flush against the jig surface perfectly. I’ve already used half the pack for a precision assembly project, and they held tight without any stripping.

The black oxide finish on these screws is flawless, no chipping or uneven spots right out of the package. I used the full box on a jig build and every thread engaged smoothly with zero binding. Solid purchase for precision work.
