براغي رأس زرية H6 M6-1 × 18mm من HOLO-KROME 86032 | محرك سداسي | سبيكة فولاذ معالجة حرارياً أسود (100/عبوة)

Installed these on a few jig fixtures and the hex socket drive made tightening them in tight spots much easier. The 18mm length was exactly what I needed for the metal plates I was assembling.

Installed a dozen of these into a jig this afternoon and the hex drive seated perfectly every time—no stripping. The black oxide finish gives them a clean, professional look that matches the rest of the assembly.

Finally a batch of button head screws where the hex socket actually fits the driver without stripping. The black oxide finish on these M6-1s has a nice consistent look across all 100 pieces.
