Captive panel screws

The PEM types PF50 and PF60 self-clinching captive panel screws keep hardware parts count to a minimum by integrating a captive screw in a spring-loaded assembly for easy and efficient handling and installation. The screws permanently mount in thin metal assemblies (0.30 in./0.8 mm), eliminating the risk of hardware falling out, getting lost, or being misplaced. Their low-profile design minimizes protrusion on front panels. When tightened, the fastener (depending on size) will protrude only 0.340 in. (8.64 mm) from the top of the sheet. The screws feature a Phillips recess as standard so they can be tightened or loosened simply using a Phillips screwdriver.  Multiple screw lengths with thread sizes from #4-40 through ¼-20 and M3 through M6 are available. They can be engineered with MAThread anticross-threads and customized with a scratchproof DuraBlack finish.PennEngineering, 5190 Old Easton Rd., Danboro, PA 18916, (800) 237-4736, www.pemnet.com
