The thermal black oxide finish on these M10 screws held up perfectly during my tooling setup, no galling after repeated use. They torqued down smoothly into my jig plate with the hex drive. Exactly what I needed for precision assemblies.

Installed a dozen of these into a jig frame yesterday and the threads cut cleanly without any binding. The 55mm length gave just enough grip for a heavy-duty clamping setup.
