Miniature fasteners enable low-cost screw-less sheet-to-sheet attachment
Type T microPEM TackPin fasteners install by first preparing properly sized mounting holes in the sheet to be attached and the base panel. After inserting the fastener into these holes, the fastener is pressed into place. The fastener clinches into the base panel and the fastener’s head subsequently holds the top sheet (as thin as 0.2 mm) firmly and permanently in place. The base panel can be as hard as HRB 45 or less on the Rockwell “B” scale and should be at least 0.89 mm in thickness for blind holes or 0.5 mm in thickness for thru holes. Upon installation, loosening due to vibration or other factors is not a concern. During the process, the fastener’s tapered tip assists in location, an interference fit eliminates hole-tolerance issues, and the self-clinching action results in full 360º metal contact. The fasteners can be installed automatically for high-volume applications. These Type T microPEM TackPin fasteners are RoHS-compliant and detailed specifications, CAD models, and performance data (Bulletin T) can be accessed at www.pemnet.com
