PEM Self-clinching fasteners

Efficient fasteners even for very thin components
In countless areas of modern industry, very thin and
very lightweight components such as metal plates,
PC boards or plastic pieces are put to use. There is
the need to permanently connect them together
securely, all the while guaranteeing high values of
torque-out and pullout. At the same time, manufacturers
expect simple, low-cost assembly.
As far back as 1942, PEM ® developed a self-clinching
fastener that was able to meet these challenges.
With increasing success and broad industry acceptance,
the product line has been continually expanded,
but even so the basic advantages have remained
the same: PEM ® self-clinching fasteners give
high-performance, are easy to install and save time
and expense.
PEM ® self-clinching fasteners are placed into a
mounting hole in the workpiece. There the selfclinching
fastener displaces material in the hole
area. This material flows by means of cold deformation
into an undercut in the region near the fastener’s
shank serrations or a special head design than
prevents the component from rotating – the selfclinching
fastener becomes an integral part of the
workpiece. In addition, PEM ® self-clinching fasteners
cause no damage or bulges on the rear side of
the workpiece. PEM ® self-clinching fasteners are
put to use in areas ranging from electronics and the
automobile industry, to the construction of machines
and apparatus, through to aeronautics and space –
and in each case they guarantee a durable, secure
anchoring.
Advantages
• Extreme load capacity even in metal sheets as
thin as 0.5 mm
• No special preparation of the mounting hole
necessary
• No recutting of threads
• Also ideal for coated surfaces
• High positional accuracy
