PennEngineering® Large knob, spring-loaded Types PF11 and PF12 - Metric PF12-M5-1

The PF12 series comprises large knob, spring-loaded captive panel screws designed for secure, repeatable access to metal panels or thin materials without loose hardware. These screws install into punched holes and retain their position after installation, with options for self-clinching, flare-mounted, or floating configurations. The series supports standard metric thread sizes, including M5, and provides a positive internal stop during installation via the shoulder on the retainer. All variants in the series feature a spring mechanism to maintain contact and allow for panel thickness variation. Available finishes include black metal or custom color plastic caps. The product is marked with the PEM® identifier to ensure authenticity.
