Process-reliable fastening with Taptite 2000 ®
Taptite 2000® screws from Arnold Umformtechnick are thread-forming
screws that, when screwed into the 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). The proven trilobular (triangular)
shape of the Taptite 2000 ® shaft has been combined with a radius
profile shape so as to optimise the tapping process.
This radius profiling corresponds roughly to an involute curve (figure
1), which allows easier flow of the nut material in the direction
of the screw thread core. Furthermore Arnold Taptite 2000® has a
low thread flank volume compared with conventional tapping screws
(figure 2), i.e. there is less forming work to be done.

The above-mentioned properties of Taptite 2000 ® reduce the
tapping torques by up to 50 percent, compared with
conventional DIN 7500 thread-forming screws.
Moreover, by using Taptite 2000®, the reliability of the
fastening process is increased and higher pre-load forces are
generated.
