براغي رأس مقبس HOLO-KROME 86062 M12-1.75 X 16mm | رأس زر محرك مقبس سداسي | فولاد سبائكي مؤكسد أسود حراري (100 / عبوة)

The thermal black oxide coating is holding up perfectly on my jig setup, no rust or flaking after a week of coolant exposure. These M12s seat cleanly with a hex key and the 16mm length is spot on for what I needed.

I’ve been using these button head screws for mounting jigs in my shop, and the black oxide coating is holding up well against minor oil splashes. The hex socket drive engages cleanly with my Allen keys, making assembly quicker than with standard Phillips heads.

The hex socket drive fits my torque wrench perfectly, and the 16mm length is spot-on for the jig I'm building. These M12 socket caps feel much more robust than the generic ones I used on the last project.
