PennEngineering® Large Knob, Spring-loaded - Types PF11M and PF12M - Metric PF12M-M3-5-2-2

The PF12M series consists of large knob, spring-loaded, self-clinching captive panel screws designed for secure fastening and repeated access to metal panels or thin materials. These screws prevent loose hardware by remaining attached to the panel after installation. They are compatible with M3 thread sizes and feature a spring-loaded mechanism for cushioned engagement. The series supports installation in panels of varying thicknesses and includes black coloring as a standard option. Mounting is achieved through self-clinching into sheet materials, with no flaring or floating variants described for this specific model designation.
