Stud, M6x40

These M6x40 studs are exactly the right length for clamping down my small milling vise, and the threading is clean and consistent. They hold tightly without wobbling, which is exactly what I needed for my bench top setup.

The black oxide finish on this M6x40 stud has held up well without any rust after several weeks in my shop. Used it to mount a small jig to my bench top and the threads engaged perfectly. Exactly what I needed for a clean, secure fit.

Threaded cleanly into every tapped hole I tried on my bench jig, and the 40mm length gave just enough grip for a spacer setup. The black oxide finish didn't flake off when I cinched down a nut with a wrench, which is exactly what I wanted.
