PennEngineering® Large knob, spring-loaded Types PF11 and PF12 - Metric PF11-M5-0

The PF11 series consists of large knob, spring-loaded captive panel screws designed for easy service access and to prevent loose hardware. These screws install into thin metal panels and are available in self-clinching, flare-mounted, or floating styles. They feature a knurled or un-knurled metal cap, with options for black metal or custom-color plastic caps. The design prevents components from falling out during maintenance. The series includes variants with different mounting and threading configurations, all sharing common structural and functional attributes for secure panel attachment with reaccess capability.
