PEM SF™ SpotFast® Fasteners create a permanent, flush joining of two metal sheets. Squeezing the fastener into place causes a cold flow of panel material into the fastener’s two separate clinch profiles. The PEM SpotFast SF fastener is designed for joining metal-to-metal. The fasteners install smoothly with the top sheet and flush or sub-flush with the bottom sheet. Fasteners can attach two metal sheets that are too difficult to weld, fasten sheets of unequal thicknesses, join dissimilar metals that cannot be welded, and attach ultra-thin metal sections.
