HOLO-KROME 76052 M4-0.7 X 6mm 內六角螺絲 | 六角形驅動 | 合金鋼熱處理黑色氧化物 (100個/包)

The black oxide finish on these M4 cap screws looks really clean and professional, and the hex drive makes them easy to snug up tight in tight spaces. They seated perfectly in a jig I’m building, no burs or rough edges at all.

I needed a handful of these for a small tooling jig, and they threaded into the tapped holes perfectly with no binding. The hex socket drive gave me a solid grip—no rounding or stripping even at a firm torque.

Exactly the right size for the jig I was building, and the black oxide finish makes them look clean and professional. These little M4 screws hold tight without any stripping.
