Easier mating-thread alignment

Paul Boughton
PennEngineering has announced two new fastening solutions: PEM fasteners with 'float' capability enable easier mating-thread alignment during attachment and promote design flexibility for relaxed tolerance applications, and PEM self-clinching concealed-head studs and standoffs which provide strong, permanent, and reusable threads for mating hardware in thin-metal assembly 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-in/1.6mm, enable subsequent access to an assembly, and compensate for up to .060-in/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.
 
PEM self-clinching concealed-head studs and standoffs provide strong, permanent, and reusable threads for mating hardware in thin-metal assembly applications. Their concealed-head feature offers design and esthetic benefits by allowing the side of the sheet opposite installation to remain smooth and untouched. This feature additionally serves as an ideal solution for applications where the host metal sheet must remain completely sealed from air, liquid, dust, gases, or other potential contaminants.
 
Concealed-head studs and standoffs install permanently in steel or aluminum sheets as thin as .062-in/1.6mm.  Studs (aluminum or stainless steel) are available in thread sizes #4-40 through #10-32 and M3 through M5 and in lengths from .250-in through 1-in and 6mm through 25mm. Standoffs (stainless steel) are offered in thread sizes #4-40 through 1/4-20 and M3 through M6 and in lengths from .187-in through 1-in and 4mm through 25mm.
