Torque wrench for interchangeable insert tools
For all assembly jobs, especially where access
with conventional sockets is not possible.
Right-hand turn for controlled screw tightening
(the torque wrench can also be used for controlled
left screw tightening, when turned over by 180°).

Calculating scale settings where an extension arm is used with the torque wrench
Each torque wrench has been specifically designed for a specific maximum scale reading and tested at this
level. For various reasons, it may be necessary in practice to add an extension arm.
To this end it is necessary to adjust the programming.
L1 x T
C =
The required settings may be calculated using the following formula:
L1 + B
L1= Length of the lever arm on the torque wrench itself
B = Distance between the two pivot centres after attaching the extension
T = Tightening torque of the bolt

C = Setting value
Example:
L1 = 425 mm
0,425 x 20

B = 40 mm
T = 20 Nm
C = ?

Torque Angle Gauge
Automotive manufacturers prescribe both torque and rotational
angle settings for fastening elements used in vehicles.
Angle controlled torquing gives initially “snug” torque, then turns
the fastener a step further to the optimum torquing angle.
Torque is measured to the maximum safe working load, while
preventing overtorquing and damage to the fasteners.
Large, easy to read scale with oil resistant,
non-reflective surface. The angle indicator
clearly indicates the angular reading.
The adjustable reference arm is firmly attached
to a non-moving part of the machine and
prevents the scale turning.
