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. Prevailing torque locknuts provide essentially the same torque value regardless of the amount of axial load applied.
FE™/FEO™/UL™ LOCKNUTS • Strong, knurled collar guarantees against rotation of the fastener in the sheet. • The torque-out resistance of the embedded knurl greatly exceeds the torque that can be exerted by the self-locking feature.
