The latest PEM SpotFast fastener permanently joins metal sheets to printed-circuit boards or plastic panels and creates a flush-attachment connection without protrusions on either side. Essentially they are alternatives to riveting or adhesives and their rotational capability extends application potential with the fastener serving as a single flush-mounted pivot point. Type SFK steel fasteners install with the top metal sheet and flush or sub-flush with the bottom panel. Standard parts can install with minimal space requirements into metal sheets as thin as 0.8mm with a hardness of 80 or less on the Rockwell B scale. Various head sizes and diameters are also available. For more details, contact Michael J. Rossi, at PENNENGINEERING, Danboro, PA. (800) 237-4736.
