PennEngineering® Large knob, spring-loaded Types PF11 and PF12 - Metric PF12-M3-0

The PF12 is a spring-loaded captive panel screw with a large knob, designed for secure attachment of thin metal panels with repeated access. It is a self-clinching fastener that installs into sheets of any hardness and provides a flush mounting configuration. The screw retains the mating nut and resists loosening due to vibration. Minimum panel thickness requirements and installed height are defined for standard applications. The PF12 is available with a black metal cap, and all variants meet PEM® quality standards with marked product identifiers. Custom sizes and colors are available upon request.
