PennEngineering® Large Knob, Spring-loaded - Types PF11MF and PF12MF - Metric PF11MF-M5-2-BL-2

The PF11MF series consists of large knob, spring-loaded, flare-mounted captive panel screws designed for secure attachment of thin metal panels with easy service access. These fasteners install flush on the back side of the panel and are suitable for use in painted panels and stainless steel applications. They feature a spring-loaded mechanism to maintain tension and prevent dislodgment during handling or service. The series accommodates multiple panel thicknesses and resists corrosion, with a standard black finish available. Flare-mounted design provides enhanced holding strength and alignment stability.
