MINIATURE SELF-CLINCHING FASTENERS PEM® brand miniature fasteners fit into a minimal space and provide strong, reusable threads. PEM miniature fasteners provide immediate visual indication when proper installation has been accomplished. A strong, knurled collar, which is 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 self-locking feature. When this collar is embedded in the sheet, the undercut cavity beneath the collar is filled with displaced sheet material thereby...

MINIATURE SELF-CLINCHING FASTENERS AXIAL STRENGTH AND TIGHTENING TORQUE COMPARISON (1) Axial strength for types UL, FEO, and FE is limited by knurled ring strength. (2) Screw strength level shown is the minimum needed to develop full nut strength, higher strength screws may be used. (3) Tightening torgue shown will induce preload of 65% of locknut min axial strength with K or nut factor is egual to 0.20. In some applications tightening torgue may need to be adjusted based on the actual K value. If screw strength is less than the value shown, tightening torgue should be proportionately...
