PennEngineering® Large Knob, Spring-loaded - Types PF11MF and PF12MF - Unified PF11MF-032-2-2

The PF11MF series consists of large knob, spring-loaded, flare-mounted captive panel screws designed for secure attachment of thin materials with subsequent access required. 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 for tool-free operation and accommodate panel thicknesses up to 0.032 inch. The design resists rotation and prevents loose hardware escape during service. The series is rated for installation into any panel hardness and supports cross-hole mounting. Standard color is black.
