The torque-out resistance of the knurl greatly exceeds the torque that can be exerted by the self -locking this collar is embedded in the sheet , the undercut cavity beneath the collar is filled with displaced sheet material thereby developing pushout /FEO /UL prevailing torque locknuts provide ideal solutions to prevent mating hardware from loosening in service due to vibration or other application-related factors.
2 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. Their use can save time and money compared with alternative chemical locking methods or dry-film lubricant applied to locking FE /FEO /UL nuts provides the smooth, non-galling prevailing torque performance necessary for reliable locking and for reusability.(1) Screws for use with PEM SELF-CLINCHING locking FASTENERS should be Class 3A/4h fit or no smaller than Class 2 /FEO /UL elliptically squeezed nuts are self -locking.
3 FE/FEO nut thread locking torque performance is equivalent to applicable NASM25027 specifications. UL self -locking nuts meet locking torque requirements specified herein. Some sizes of FE/FEO/UL nuts can be ordered to NASM45938/7 specifications (2). For more information on NASM25027 as applied to PEM SELF-CLINCHING , self -locking nuts, check our web site for tech sheet PEM - /FEOX /U non-locking nuts have class 2B/6H strong reusable threads. These FASTENERS can be installed into thinner sheets and closer to the edge of a sheet than standard SELF-CLINCHING nuts. Some sizes of FEX/FEOX/U nuts can be ordered to NASM45938/7 specifications (2).(1) Consult Bulletin LN for complete line of SELF-CLINCHING , locking FASTENERS .
