About Product
PEM® brand miniature fasteners fit into a minimal space and provide strong, reusable threads.Types FE, FEO and UL are self-locking. Types FE and FEO thread locking torque performance is equivalent to applicable NASM25027 specifications. Type UL self-locking nuts meet locking torque requirements specified herein. Some sizes of FE, FEO, and UL can be ordered to NASM45938/7 specifications. Types FEX, FEOX and U have free-running class 2B/6H threads.PEM miniature fasteners provide immediate visual indication when proper installation has been accomplished.A strong, knurled collar, which is completely embedded in the sheet, guarantees against rotation of the fastener in the sheet. The torque-out resistance of the knurl greatly exceeds the torque that can be exerted by the selflocking feature.When this collar is embedded in the sheet, the undercut cavity beneath the collar is filled with displaced sheet material thereby developing pushout resistance.A dry-film lubricant applied to these fasteners provides the smooth, non-galling prevailing torque performancenecessary for reliable locking and for reusability.
