Fasteners Join Metal Components
Pairing with a compatible wave washer, PennEngineering’s PEM SpotFast Type SFW self-clinching fasteners create a flush-attachment connection between two thin metal parts in applications requiring repeatable pivoting or hinging action. The steel components have zinc plating with lubricant, can attach dissimilar metals or sheets with different thicknesses, and work in steel or aluminum sheets as thin as 0.031” with hardness of 80 or less on the Rockwell “B” scale. The RoHS-compliant products install by preparing a properly-sized hole in both panels, putting the fastener in one panel, placing the wave washer over the installed fastener, and situating the second panel over the fastener. Sufficient squeezing force installs the fastener smooth with the top sheet and flush or sub-flush with the bottom sheet.
