Product description

Mechanical Nut Runner MDS

For manual tightening and loosening of bolt connections up to 10,000 Nm. All ITH nut runners operate by the torque method.

Design

All ITH nut runners use a planetary gearbox. All nut runners are divided by their size and torque multiplying set in various types. The reaction arm of every type has a fine-toothed connection; this is adjustable in every way and can be customized on your needs.

Safety equipment

To avoid overload of the maximum torque an overload protection (shear pin) is used inside the square drive. The back stop stops the turning back of the bolt. It can be switched for tightening or loosening.
Various sockets are available from ITH (hexagon sockets, hexagon drives, and many more). All the inserts can be changed individually by removing the security clip. More information is available in the accessories section for nut runners. Accessories for Nut Runners.

Function description

The primary torque values from the manual nut runner are shown in the data table. The switch of the back stop switch has to be set to loosen or tighten (L/R). It is necessary to put the reaction arm in a secure position before using the tool.
