PEM Types PF50 and PF60 self-clinching captive panel screws from Penn Engineering keep hardware parts count to a minimum by integrating a captive screw in a spring-loaded assembly to promote easy and efficient handling and installation. Their permanent mounting in thin metal assemblies additionally eliminates any risks associated with loose hardware that could fall out, get lost, or misplaced and potentially cause damage to internal components. These fastener solutions suit panels, covers, drawers, racks, and other access points where secure attachment and subsequent access will be necessary. Their low-profile design minimizes protrusion on front panels to satisfy particular functional and cosmetic requirements. When tightened, the fastener (depending on size) will protrude only .340"/8.64mm from the top of the sheet.
