Industrial applications:
Fastening of indexable cutter inserts
In the metal cutting industry, great
importance is attached to process
safety. When changing indexable cutter
inserts, this can only be ensured by
using
torque tools.
Sensitive fastenings in the
ESD protected zone
Printed circuit boards and
electronic semiconductor components
react extremely sensitively to mechanical
loads. The correct torque guarantees
secure installation of cost-intensive
materials.
Circular plug connector -
protection class IP67
For correct functioning of distributions
systems on machines, the correct torque
must be observed when connecting the
circular plug connectors. Otherwise the
protection class IP67 cannot be com-
plied
Smartphones and Co.
Today's electronic devices are always
smaller and more efficient.
This makes smaller screws necessary
which are fastened in sensitive materials
such as plastic. Without the correct
torque, these screws are damaged or
the plastic
Installation of glass elements
Particularly for materials such as glass
which react sensitively to pressure and
tension, fastening with the recommen-
ded torque is a prerequisite.
Electrical devices in outdoor areas
This type of device must be protected
from penetrating humidity and are e.g.
subject to the protection class IP67.
In order to ensure this, all housing
screws must be tightened with the
torque according to man
Solar technology
Overtightened screws can damage the
sensitive photovoltaic modules.
In contrast, secure fastening cannot
be guaranteed with screws which
are not tightened enough.
Composite materials
The use of new materials such as
carbon make using torque tools vital.
The carbon structure is damaged by the
incorrect torque during fastening. Be-
cause of this, the material no longer with-
stands the requirements.
Trade applications
76
Wiha torque screwdrivers.
Diverse areas of application in trade and industry.
New materials –
sensitive electronic components
in extremely tight spaces –
automated processes in production
technology – just a few of many
examples that illustrate how
rapidly industrial and trade
applications are developing.
The demands for correct fastening
of components also grow with
these changes. Only in this way for
example is it possible to eliminate
protection from humidity or
the danger of damage to
materials in production processes.
Industrial installations
Using torque tools is vital to assure an
uniformly high quality in manufacturing.
Type-tested switching devices
For type-tested switching devices,
the torque to be observed is specified by
all manufacturers to prevent the
formation of glowing contact areas.
