The nylon pellet locks these down tight—I've had zero backing-out issues on my jig even with constant vibration. The black oxide finish looks sharp and seems to resist any minor rust so far.

The hex socket drive seated perfectly on my Allen key, and every single screw in the bag threaded cleanly into my jig without any stripping. The thermal black oxide finish feels slick and uniform, which made them easy to handle during assembly.

The black oxide finish on these is what sold me—they slip into my jig setup without any galling, and the nylon pellet holds tight even after a few removals. For a hundred pieces at this price, I’ve got no complaints about the threading either, it’s clean all the way down.
