HOLO-KROME 64012 براغي مقبس سداسي #6-32 × 1/2 بوصة | رأس زر مع محرك سداسي | فولاذ سبائكي مع أكسيد أسود حراري (100/عبوة)

I needed a batch of these for a small jig build and the hex socket drive made installation much cleaner than using a standard slotted screw. The black oxide coating seems durable so far with no flaking after tightening.

The hex socket drive fits my allen wrench perfectly with zero stripping, and the button head profile sits flush on my jig fixture. These screws tightened down evenly without binding, exactly what I needed for a precision assembly.

The black oxide finish on these screws looks clean and holds up well on the tools I’ve used them on, and the hex socket drive made tightening them in tight spots a breeze. Pack of 100 is solid value for precision assembly work.
