A four-page product bulletin from PennEngineering profiles PEM® self-clinching blind fasteners designed to provide barriers that protect threads against foreign matter and protect circuits from intrusion of extra-long screws. Bulletin B reviews specifications, performance data and the installation procedure for the blind-type fasteners, which employ a self-clinching design enabling permanent installation in thin metal sheets. The fasteners act as their own pilot and, being round, do not require indexing. The steel (Type B) and stainless steel (Type BS) fasteners can provide permanently mounted blind threads in metal sheets as thin as 0.040 inch/1 mm and are available in thread sizes #4-40 through 1/4-20 and M3 through M6. Blind fasteners in each thread size are offered in two different shank lengths to meet the specifications of design engineers who want panel holes refilled as much as possible. The fasteners are RoHS compliant.
