TAPTITE 2000® – Thread-rolling in metals

Application in solid steel

Torque sequence in core ECO Air COMPACT axis with
hole area 7.40 + 0.1mm in disc brakes.
overturn test
Screw fastening for ABS sensor made with TAPTITE
2000® M8 10.9 Corflex® I.

Torque sequence in core hole area
7.40 + 0.1mm in overturn test.

It is possible to make a screw fastening with a typical
tightening torque of ~ 30 Nm. Despite the higher
strength of the steering knuckle (hardened and
tempered to ~ 900 MPa) it is still possible to make a
reliable thread-tapping fastening.
However additional inductive hardening at the tap-
ping zone is necessary.
