FDS® Screw Fasteners

It is the FDS’ ability to increase thread engagement in the through draught that
makes it a unique metal fastener. The metric female thread forms without creating
chips during the insertion process creating a backlash-free thread engagement
that is waterproof, gastight and able to withstand both high pullout and shear forces.

The heat generated by the piercing action of the FDS falls well within all safety
limits but still gives exactly the right expansion of the joint to create high dynamic
safety as shrinkage takes place.

Several types of the FDS metal fastener have been developed to provide a
solution for a wide range of assembly propositions; from fully automatic assembly
through to manual assembly options, with and without the need for pilot holes
as with other screw fasteners. In manual fixing applications there are endless
examples where part reduction has been a significant enough reason to choose
FDS and the fastener has been adapted for cover fixings over electrical contact
areas on microwave ovens, refrigerator door handle assemblies, electric oven
interiors and drum assemblies in washing machines; the latter because of the
screw fasteners strength and resistance to vibration. Beside providing one-sided
access and extreme high strength, the fastener is designed to remove easily,
especially if application recycling is key.
