PEM ® FASTENERS ANDPEMSERTER ® PRESSESPEM fasteners provide strong, quality threadsin metal and P.C. boards too thin to be tapped.PEM fasteners are easily installed byinserting them into punched or drilledholes and applying parallel squeezingforces. In ductile materials, as the installationforce is applied, part of the sheet cold flows into an undercut beneath thehead thereby making the fastener an integral part of the sheet. A serratedclinching ring prevents the fastener from rotating once installed.PEM brand broaching fasteners for printed circuit boards and nonductilematerials are pressed into drilled mounting holes and heldpermanently in place by an interference fit. Both self-clinching andbroaching designs withstand substantial pushout and torque-out forces.TRADEMARKSTo help you identify genuine PEM ® brand fasteners,most are marked by one of our registeredtrademarks – “PEM” or “one and two groove”trademark on internally threaded fasteners and a“recessed dimple” on the ends of studs. To be sureyou are getting genuine PEM ® brand fasteners lookfor the PEM ® Trademarks.Dimple onstuds.Two grooveson nuts.“PEM” stampon top of nuts.PEM Fastening Systems also offers weld nuts. PEM weld nuts are roundthereby eliminating indexing, and have pilot shanks so that they are selflocatingin panel holes and protect threads from weld splatter.PEM brand fasteners are available in many variations as indicated on thefollowing pages. Selections of threaded fasteners include free-running,self-locking, floating, and blind hole types meeting Unified, ISO, andMIL standards. They are available in carbon steel, stainless steel, andaluminum.Also available is hardware for special industry applications such asCONNECT’R WARE ® fasteners for connector mounting, AUTOSPEC ®fasteners for automotive applications, and SI ® brand inserts for plastics.Our new STICKSCREW ® system offers manufacturers an extremely fast,accurate and efficient method of small screw insertion.Two grooveson standoffs.Double squaresfor floating nuts.One groovefor PEM 300 ®nuts.The color bluefor nylonlockingelements.PEMSERTER presses are designed to safely, reliably, accurately, andquickly install PEM fasteners. When using PEMSERTER presses toinstall PEM fasteners the entire fastener installation process isstreamlined. No matter how complex or simple an installation challengemay be, using the PEM fastener and PEMSERTER press system willprovide you with quality results.The bulletin designation and date can be found at the bottom right of eachproduct bulletin. Fastener bulletins appear alphabetically in the catalog bybulletin designation. Information on PEMSERTER ® fastener installationpresses can be found on pages 7 and 8 of this product guide.PEM Fastening Systems has been manufacturing these quality fastenerssince 1942. Today, PEM self-clinching fasteners are used throughout theworld by manufacturers of electronic, communications, aerospace, andautomotive equipment.PEM ® fasteners and PEMSERTER ® presses are briefly described on thefollowing pages.
