PennEngineering® Large knob, spring-loaded Types PF11 and PF12 - Unified PF12-032-0

PF12 captive panel screws are spring-loaded, large-knob fasteners designed for secure attachment of thin metal panels with reusable access. They install into punched holes and retain the screw post-mounted to the panel, preventing loose hardware. The screw features a knurled or smooth metal cap and is compatible with multiple panel thicknesses and circuit board applications. Installation requires no special tools, and the design accommodates misalignment. The part is available in self-clinching mounting style and meets PEM® quality standards with registered markings for authenticity.
