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

The PF12MF is a large knob, spring-loaded, flare-mounted captive panel screw designed for secure attachment of thin metal panels with subsequent access required. It installs flush on the back side of the panel and accommodates panels of any hardness. The design prevents loose hardware by retaining the screw in place through the flare mount, and it is suitable for applications requiring alignment and vibration resistance. The part is available in metric thread sizes and features a black finish. Standard color options and installations include support for stainless steel panels and printed circuit boards. All variants in the PF12MF series share these core characteristics.
