S-RT Free Running Locknuts
Product Details
New PEM® S-RT™ free-running lock-nuts allow the mating screw to be spun on freely until clamp load is induced. Unlike other thread locking systems the screw runs freely until the final clamp load is reached and provides superior resistance to vibration.
Features of the RT Free-Running Locknuts include:
Screw turns freely until a clamp load is applied. No friction as with nylon inserts or other thread locking nut systems
Resistant to vibrational loosening
Superior anti-vibration properties to standard hex nut and spring washer
When installed with a suitable press, the mating side of the metal sheet will be flush or sub-flush
Locking feature reusability is not affected by number of on/off cycles
Reduce assembly time and inventory by taking separate locking washers out of the assembly
Uses same mounting hole and installation tooling as standard S type PEM self-clinching nuts – no special changes to the panel or installation process required
Available in M3 to M6 thread plus unified sizes.
