HOLO-KROME 76436 براغي رأس سداسية M16-2 × 45 مم | محرك سداسي | صلب سبائكي أسود حراري (25 / عبوة)

I’ve been swapping out the standard hardware on my jigs and these M16s are spot on, the hex socket drive makes seating them deep in tight spots so much easier. They’re rigid and the thermal black oxide has that consistent, matte look that holds up better than I expected.

The black oxide finish on these screws held up perfectly during assembly, no chipping or flaking. Thread engagement was smooth and consistent across all 25 pieces.

The packaging alone tells you these are quality—each screw sits snug in its tray, and the black oxide finish is consistent across all 25. Fit the M16 thread perfectly into my jig plates, and the hex socket grabbed without any stripping.
