PennEngineering® Large knob, spring-loaded Types PF11 and PF12 - Unified PF12-832-1

PF12 captive panel screws are spring-loaded, large-knob fasteners designed for secure attachment of thin metal panels with easy access for service. They install into sheet materials via self-clinching and feature a retainer with shoulder to prevent over-insertion. Performance data for the PF12 series indicates a retainer pullout force of 3000 lbs in aluminum and 4500 lbs in cold-rolled steel, with installation force of 100 lbs in aluminum and 160 lbs in steel. The MF and MW variants are flare-mounted, but PF12 is not listed with those options. Color, threading, and tool-specific variants are available but not specified for PF12-832-1.
