PEM® fasteners with unique “float” capability enable easier
mating-thread alignment during attachment and promote design flexibility for
relaxed tolerance applications. The family of floating fasteners includes
captive panel screws (Types PF11MW™ and PF12MW™) and self-clinching nuts (Types
AS, AC, LAS, LAC, A4, and LA4). All install easily and permanently in thin
sheets.
Floating captive panel screws (Type PF11MW with knurled cap
and Type PF12MW with smooth cap) reliably install into metal or non-metal
panels as thick as 0.63” /1.6mm, enable subsequent access to an assembly, and
compensate for up to .060” / 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.
Floating self-clinching nuts can be specified with
non-locking threads (Types AS, AC, and A4) or self-locking threads (Types LAS,
LAC, and LA4). They provide permanent load-bearing threads in metal sheets as
thin as .038” / 0.97mm and permit a minimum of .030” / 0.76mm adjustment for
mating hole misalignment. Their unique 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 1/4-28 and M3 through M6. Types
A4 and LA4 fasteners specifically are designed for use in stainless steel
sheets.
