PEM Brand Nuts for Sheet Metal
Miniature Self-Clinching Nuts
PEM® brand miniature fasteners fit into a minimal space and provide strong, reusable threads. PEM miniature fasteners provide 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 developing pushout resistance.
