براغي HOLO-KROME 76850 M14-2 X 90mm ذات رأس أسطواني | محرك سداسي | فولاذ سبائكي أسود حراري (25 / عبوة)

Installed these in a jig frame and the threads ran smooth all the way down, no binding at all. The black oxide finish has a nice even look straight out of the package.

I needed a set of precise fasteners for a custom jig build, and the 90mm length on these M14 screws was exactly right for the clamping depth I required. The hex socket drive made installation straightforward with no stripping, and the thermal black oxide coating seems durable.

The black oxide finish on these M14 screws looks professional and the threads cut cleanly into my jig fixture without binding. Worked perfectly for mounting a heavy-duty tooling plate.
