PennEngineering® Large knob, spring-loaded Types PF11 and PF12 - Metric PF12-M6-2-BL

The PF12 series comprises large knob, spring-loaded captive panel screws designed for secure attachment of thin metal panels with repeated access, eliminating loose hardware risks. These screws install into panels via self-clinching and feature a spring-loaded mechanism for tool-free operation. The design includes a shoulder on the retainer to provide a positive installation stop. Available in metric threading, with options for knurled or unknurled metal caps and black caps, the series supports mating with standard screwdrivers and accommodates panel thickness variations. All variants meet PennEngineering's quality standards and are identifiable by the PEM® dual squares trademark.
