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.

Easy to use,

precision work:

Magnifying window scale enables easy, accurate read-off.

Strong, reversible ratchet, 32 teeth, 11.25° pivot range.

Aspring-loaded ball ensures the sockets are firmly attached and

cannot fall off. The release mechanism enables sockets to be

removed and changed quickly at the push of a button.

The required torque is quickly set via a pull-out setting knob

in the handle.

When the preset torque is attained, the wrench produces both

audible and tactile signals.

Right-hand turn for controlled screw tightening.

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.

The required settings may be calculated using the following formula: C = L1 x T
