PEM® PFC4™ self-clinching captive panel screws from PennEngineering® install permanently into stainless steel enclosures to enable easy access whenever necessary and eliminate risks associated with loose screws. The captivated screw remains reliably in place where designed in a door or panel and will not loosen, fall out, or damage internal components. Expanding their application potential, these spring-loaded fastener assemblies comply with UL 60950 equipment access standards.
PFC4 captive panel screws will install successfully in stainless sheets as thin as .060” / 1.53mm with hardness up to HRB 88. A shoulder provides a positive stop during installation and the fastener ultimately will be flush on the opposite side of the sheet for a clean and unmarred appearance. A fully recessed head in the fastened position allows for tool-only access.
The fasteners are manufactured from 400 Series stainless steel providing corrosion resistance comparable to zinc-plated steel. They are available in assorted screw lengths and in thread sizes #4-40 through #10-32 and M3 through M5. All PFC4 fasteners are RoHS compliant.
Among options, designers can specify MAThread® anti cross-thread technology as a safeguard to correct off-angle thread mating and promote proper alignment during installation. A Torx® recess offers an alternative to the standard Phillips drive.
PFC4 captive panel screws are part of a growing family of PEM® access hardware solutions. Detailed specifications, fastener drawings and 3D models, and performance data (Bulletin PF) can be viewed and downloaded for free at www.pemnet.com.
