The PF11M series consists of large knob, spring-loaded, self-clinching captive panel screws designed for secure attachment to thin metal panels with easy subsequent access. These fasteners feature a retained screw to prevent loss and are compatible with M3 threading.

All variants share the same self-clinching installation method and are marked with PEM® identifiers for authenticity.
