HOLO-KROME 86012 M4-0.7 X 15mm براغي غطاء مقبس | رأس زر بمحرك مقبس سداسي | فولاذ سبائكي أسود حراري (100/عبوة)

These little button heads have been perfect for my jig builds—the hex socket grabs cleanly every time and the thermal black oxide gives them a nice, uniform look that resists scuffs. Exactly the consistent quality I needed for precision assemblies.

The black oxide finish on these M4 screws holds up well in tight spaces, and the button head gives a clean look on my precision assembly. The socket drive made installation straightforward even in a cramped jig.

Honestly, I grabbed these for a jig I'm building and the black oxide finish is way more uniform than I expected for a bulk pack. The hex socket drive bit down cleanly and I didn't strip a single one across all 20 I've used so far.
