براغي رأس أسطوانية HOLO-KROME 76838 M14-2 × 60 مم | محرك سداسي | فولاذ سبائكي مؤكسد أسود حراريًا (25/عبوة)

Had to replace a stripped bolt on a heavy-duty jig and these M14 screws fit perfectly, the hex drive made installation simple. The alloy steel feels solid and the black oxide coating seems resistant to the shop oil. Exactly what I needed for the rebuild.

The black oxide finish on these M14 screws held up perfectly in my shop press, no rust after a week of coolant exposure. Threads cut cleanly into my tool steel jig plate without binding.

Installed these in a jig for a production run and they torqued down perfectly without any stripping. The 60mm length was exactly what I needed for the assembly.
