Self-clinching studs and nuts are available with a special Teflon coating used to mask the threads and prevent adhesion of undesirable substances to external and internal threads. The coatings can be applied to precise areas of all materials and finishes to protect threads from electro-deposited platings, primers, paint, and weld splatter. The coatings also add lubricity to fastener threads, reducing driving friction, heat buildup, and thread galling.
