Fasteners

Available with a float capability that enables easier mating thread alignment during attachment and promotes design flexibility for relaxed tolerance applications, PEM’s family of RoHS-compliant floating fasteners includes type PF11MR knurled cap and PF12MW smooth cap captive panel screws and types AS, AC, LAS, LAC, A4 and LA4 self-clinching nuts. They install easily and permanently in thin sheets. The panel screws install into metal or non-metal panels as thick as 1.6mm, enable subsequent access to an assembly, and compensate for up to 1,52mm mating hole misalignment. Patented MAThread anti-cross threading technology corrects off-angle installations, aligns components, and slides through clogged internal threads, and a shoulder on the retainer portion of the fastener helps simplify installation. Thread sizes range from #4-40 through ¼-20 and M3 through M6 and available options include a scratch-proof DuraBlack finish. Assorted colored plastic caps are also available. The self-clinching nuts can be specified as non-locking (Types AS, AC, and A4) or self-clinching threads (Types LAS, LAC, and LA4). They provide permanent load-bearing threads in metal sheets as thin as 0.97mm and permit 0.76mm adjustment for hole misalignment. Their design allows the fastener’s threads to extend fully into the retainer shank to impart added strength and support in an assembly. Thread sizes range from #4-40 through ¼ -28 and M3 through M6. Types A4 and LA4 fasteners specifically are designed for use in stainless steel sheets.
