MINIATURE SELF-CLINCHING FASTENERS

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 1. Prepare properly sized mounting hole in sheet. Do not perform any secondary operations such as deburring. 2. Insert fastener into the anvil hole and place the mounting hole (preferably the punch side) over the shank of the fastener as shown in the drawing. 3. With installation punch and anvil surfaces parallel, apply squeezing force to the knurled collar until knurled collar is flush with top of the sheet for sheets .060 /1.5mm thick and up, or until shank is flush with the bottom of the sheet for sheets .04071mm to .06071.5mm thick for Type FE/FEO.
