Press Release Summary:
PEM® S-RT™ Self-Clinching Free-Running Locknuts feature thread angle which allows user to tight mating screws. Unit can be used with aluminum or steel sheets of .030 in./0.8mm size. Product is suitable for thin metal assembly and sheet-to-sheet attachment applications.
Original Press Release:
New PEM® S-RT™ Free-running Locknuts
New PEM® S-RT™ self-clinching free-running locknuts from PennEngineering® feature a modified thread angle enabling easier tightening of mating screws and superior vibration-resistant locking performance in thin metal assemblies. The modified thread formation allows mating screws to spin freely during the attachment process until clamp load is induced during the screw-tightening process. The applied clamp load then engages the locknut’s vibration-resistant locking feature, which securely and reliably locks the screw in place. Compared with traditional locknuts, excellent joint clamp load remains consistent, even after many on/off cycles.
PEM S-RT self-clinching locknuts install into aluminum or steel sheets as thin as .030"/0.8mm and become permanent parts of an assembly. Upon their installation using a PEMSERTER® or other standard press, the back side of the host metal sheet for screw insertion will be flush or sub-flush and the assembly side will be flush or sub-flush ideally suiting sheet-to-sheet attachment applications.
