PEM (PennEngineering) TK4™ microPEM® TackSert® Pins enable the attachment of metal sheets to plastics and PCBs, replacing costly screw installations in applications where disassembly is not required. These TK fasteners are ideal for more brittle materials, and a helical knurl with an undercut just below the fastener head helps create an interference fit that frictionally resists pull-out. The simple press-in installation does not require heat or ultrasonics, and it eliminates the costs and concerns associated with micro screws. These pins feature a registered trademark PEM dimple design and are easily installed automatically, offering a tapered tip for alignment and a low-profile head for space savings. The TK4 microPEM TackSert series is ideal for automotive applications, wearables, laptops, tablets and eReaders, smartphones, and gaming devices.
