SELF-LOCKING FASTENERS
LN SELF-LOCKINGFASTENERSPEM self-clinching locknuts prevent mating hardware from LN-218LN-2 PennEngineering FASTENERSPEM SELF-CLINCHING LOCKNUTS PREVENT MATING HARDWARE FROM LOOSENINGPEM self-clinching locknuts provide ideal solutions to prevent mating hardware from loosening in service due to vibration or other application-related factors. This family of FASTENERS includes a variety of types and different locking-feature styles to satisfy a wide range of applications. Their use can save time and money compared with alternative chemical locking methods or LOCKING THREADSPEM locknuts include two locking designs:1) PREVAILING torque (CFN , FE , FEO , UL , LAS , LAC , LA4 , LK , LKS , LKA , PL , PLC and SL locknuts) a design feature of the lock nut produces friction between threads of mated components thereby increasing the force needed to tighten as well as loosen the nut.
