PennEngineering® Large knob, spring-loaded Types PF11 and PF12 - Unified PF12-032-2

The PF12 series consists of large knob, spring-loaded captive panel screws designed for secure attachment of thin metal panels with repeated access required. These fasteners install into standard sheet thicknesses and feature a spring-loaded mechanism to maintain panel retention during disassembly. The series includes self-clinching and flare-mounted variants with options for knurled, un-knurled, or black metal caps. No dimensional or performance details specific to PF12-032-2 are listed, but the base design common to all PF12 variants includes a shoulder on the retainer that provides a positive installation stop. Custom sizes and colors are available on special order.
