PennEngineering® Large Knob, Spring-loaded - Types PF11M and PF12M - Metric PF11M-M4-0-2

The PF11M series consists of large knob, spring-loaded, self-clinching captive panel screws designed for secure fastening and easy access in applications requiring repeated service. These screws install into thin metal panels and retain the fastener assembly to prevent loose components. They feature a knurled or unknurled metal cap and are compatible with M3 and M4 thread sizes. The series supports installation in stainless steel and painted panels, with an anti-corrosion finish and available in black. A shoulder on the retainer provides a positive stop during installation.
