PennEngineering® Large Knob, Spring-loaded - Types PF11M and PF12M - Unified PF11M-440-1-2

The PF11M series consists of large knob, spring-loaded, self-clinching captive panel screws designed for secure attachment of thin metal panels with easy service access. These fasteners feature a knurled or unknurled metal cap and are intended for applications requiring repeated access without loose hardware. Installation is facilitated by a shoulder on the retainer that provides a positive stop. The series is compatible with various panel thicknesses and materials, and includes options for different thread sizes and lengths. All members of the series share the same mounting and actuation characteristics as specified for PF11M-type fasteners.
