HOLO-KROME 64086 براغي رأس مقبس 5/8-11 × 1-1/4" | رأس زر بمحرك مقبس سداسي | فولاذ سبائكي بأكسيد أسود حراري (25 / عبوة)

Installed these on a jig fixture and they fit the button head socket perfectly. The 1-1/4" length was just right for my assembly, and the black oxide coating should hold up well against shop grime.

Installed these in a jig I'm building and the hex socket drive seated perfectly without any stripping. The 5/8-11 thread engagement feels solid and the button head profile gives a much cleaner look than standard cap screws.

The black oxide finish on these screws gives them a nice uniform look, and the button head profile sits flush against my jig plates without catching on anything. I've tightened several down with a hex key and the socket drive holds up without stripping.
