Datasheet
Datasheet Summary
Powered by GS/AI

The PF12M series consists of large knob, spring-loaded, self-clinching captive panel screws designed for secure attachment of thin metal panels with repeated access. These fasteners retain the screw in place during servicing to prevent loose hardware. The series is available with a black-painted finish and supports installation into panels of varying hardness, including stainless steel. Variants include flared and floating options, but the PF12M model is specifically self-clinching. All models in the series feature a spring-loaded mechanism and are marked with PEM® identifiers for authenticity.
