PennEngineering® Large Knob, Spring-loaded - Types PF11MW and PF12MW - Metric PF11MW-M5-1-1

The PF11MW series consists of large knob, spring-loaded, flare-mounted, floating captive panel screws designed for applications requiring compensation for mating hole misalignment and installation into panels of any hardness. These fasteners are intended for metal panels or thin materials where repeated access is needed, and they prevent loose hardware risks. The series includes metric threads and is marked with PEM® identifiers for authenticity. All variants share the same fundamental design and functional attributes, including spring-loaded floating capability and compatibility with various panel thicknesses and materials.
