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

The PF12M series consists of large knob, spring-loaded, self-clinching captive panel screws designed for secure attachment of thin metal panels with reliable re-access. These fasteners feature a spring-loaded mechanism that maintains tension and prevents detachment during panel removal. The series includes variants with metric threading, and black finish options are available. Installation retains the screw in the panel, eliminating loose hardware risks. Dimensions and performance data are consistent across the PF11M/PF12M/PF15M family, with standard thread sizes and installed height profiles defined for M3 applications. All variants meet PEM® quality standards and are marked with registered identifiers for authenticity.
