PennEngineering® Large Knob, Spring-loaded - Types PF11M and PF12M - Unified PF11M-632-1-BL

PF11M series captive panel screws are spring-loaded, self-clinching fasteners designed for secure attachment of thin metal panels with repeated service access. They feature a large knob for manual actuation and are installed into panels with sufficient hardness to retain the clinched shank. The series includes variants with black metal caps and accommodates mating threads in stainless steel and circuit board materials. Installation ensures a positive stop via the shoulder on the retainer, and the fasteners are available with multiple threading options and custom color caps. All variants share the same core design and mounting methodology as defined for the PF11M series.
