PennEngineering® Large knob, spring-loaded Types PF11 and PF12 - Metric PF11-M3-0-BL

The PF11 series consists of spring-loaded, self-clinching captive panel screws with a large knob, designed for secure attachment of thin panels where repeated access is required. The PF11-M3 variant has an M3 thread size and provides a retainer pushout force of 11.1 kN in cold-rolled steel and 6.7 kN in aluminum. It is available with a black cap, as indicated by the 'BL' suffix in the part number, which corresponds to the standard black color option noted for the series. The design eliminates loose hardware and includes a shoulder on the retainer for positive installation stop.
