Finally got around to swapping out some stripped bolts on a jig, and these M16s seated cleanly without any binding. The thermal black oxide coating feels slick and looks properly done, not just painted on. Threads were consistent across all ten pieces, which is what I needed for a precise assembly.

The black oxide finish on these screws is flawless—no flaking even after I torqued them down on a fixture. The hex socket drive seated perfectly with my Allen key, and the M16 thread engagement felt solid on the first pass.
