PennEngineering® Large Knob, Spring-loaded - Types PF11MF and PF12MF - Unified PF11MF-632-1-BL

The PF11MF series consists of large knob, spring-loaded, flare-mounted captive panel screws designed for secure attachment of thin panels with subsequent access requirements. These fasteners install flush on the back side of the panel and are suitable for use with painted or stainless steel panels. They feature a spring-loaded mechanism to maintain tension and prevent loosening, and are available in standard black finish. The series accommodates threading misalignment and installs into panels of varying hardness without requiring high installation force.
