Taptite 2000® – Thread-forming screws with optimised
flank geometry
Why are thread-forming screws used?
Thread-forming screws are fasteners that, when screwed into core
holes, create their own female thread by means of a non-cutting
forming process.
A standard commercial metric screw can also be screwed into the
formed thread (providing compatibility, for example in the event
that a repair is required).
In recent years the use of thread-forming screws in industry has
greatly increased. The main reason for this is to save costs
during the production process, because there is no need for
thread-cutting, cleaning, checking, or for tools etc. In the case
of cast holes, for example in aluminium castings, there is no need
for drilling. So the overall costs of a screw fastening can be
reduced by up to 85%.
Furthermore, thread-forming screws are very secure against coming
loose. This also generally means that there is no need for
additional screw retention devices.
Moreover, during the thread-forming process, the nut material is
cold work hardened, and this also improves the mechanical
properties of the female thread.
Over the years ARNOLD UMFORMTECHNIK, based in
Forchtenberg-Ernsbach in Germany, has become a leading development
partner in fastening technology. Its slogan means “solutions that
connect”. ARNOLD UMFORMTECHNIK works together with well-known
companies in the automotive and electronics industries. Every day
