The PEM® SpotFast™ self-clinching fastener from Penn Engineering creates a permanent, flush joining of two sheets of metal. The fastener installs smooth with the top sheet, and flush or sub-flush with the bottom sheet. Squeezing the fastener into place causes a cold- flow of panel material into the fastener's two separate clinch profiles. This fastener is capable of joining two dissimilar metals, including unequal thicknesses. Rotational by design, the use of a single fastener can also act as a hardened pivot point if so desired.Quantity Discount Available.
