Self-Clinching Captive Panel Screws


PEM PFC4 self-clinching captive panel screws 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 in. / 1.53 mm 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.
