Threaded Fasteners for plastic - Infastech

FasTening & assembly soluTions For PlasTic aPPlciaTions
Plastics continue to open up a world of
design opportunities, yet present some
unique fastening problems. Whether
you’re fastening plastic to plastic or
plastic to another material, Infastech
offers a wide selection of high-
performance fasteners engineered to
meet the requirements of your
application.
selecTing The righT FasTener
With thousands of different polymers
available today, there can be no absolute
guidelines to follow when fastening these
materials. Laboratory testing of fasteners in
the subject material is the only way to
determine if acceptable performance levels
can be achieved.
For maximum performance, a fastener should
be selected early in the design process.
Infastech applications engineers are available
to help you every step of
the way, from selection and testing to
boss design.
Why use sPecial FasTeners For PlasTics?
Each type of plastic has its own set of
performance issues, such as ductility, thermal
expansion and clamp retention. Selecting a
fastener that can best match these
requirements is critical to the overall
performance of an application.
Type B, type AB and other standard fasteners,
with wide flank angles and shallow threads,
were designed for use in sheet metal and can
not meet the dynamic requirements of
plastics.
oPTimal PerFormance
Fasteners specially designed for plastics can
optimize performance in specific types of
materials. By selecting the proper fastener,
you may obtain:
• Higher strip-out torque values
• Increased resistance to loosening
• Higher pull-out values
reduced in-Place cosTs
Proper fastener selection may allow the use of
thinner bosses and eliminate the need for
supplementary locking devices. This can
reduce in-place costs through:
• Reduced material usage
• Reduced cycling times
• Elimination of inserts and adhesives
• Streamlined assembly
