Norbar Torque Tools' Model 5 miniature torque wrench offers the convenience of interchangeable 1/4 inch hexagonal bits as well as a 1/4 inch square drive

Norbar Torque Tools Ltd is pleased to introduce the Model 5, a unique high accuracy 1-5 Nm miniature torque wrench that offers the convenience of interchangeable 1/4 inch hexagonal bits as well as a 1/4 inch square drive.

The Model 5 is accurate to +/-3%, which exceeds the +/-4% tolerance allowed by ISO 6789 for torque wrenches and is half the +/-6% allowed by the standard for screwdrivers.

This high accuracy makes the Model 5 ideal for light assembly work in electro-mechanical applications such as automatic gearboxes and fuel injection systems, the electronics industry, aero and model engineering.

Unlike most other miniature torque wrenches the Model 5 remain accurate regardless of the hand position on the wrench.

Also, possibly unique to a torque wrench, the Model 5 accepts standard 1/4 inch hexagon bits.

While the wrench comes supplied with a 1/4 inch square drive this can be instantly removed and replaced with another fitting.

The Model 5 comes with a carrying case which has space for storage of additional bits and the optional stepless ratchet.

Each Model 5 also comes with a traceable calibration certificate issued by Norbar's UKAS accredited laboratory to satisfy an ISO 9000 quality assurance system.

Pre-set "P" Types are also available for applications where users are not authorised to adjust the torque setting.

The pre-set versions have a scale so the torque setting can be seen at a glance but not adjusted.

"P" types are supplied with coloured end seals to identify the wrench for example to the torque setting or a particular operator.

Both the adjustable and pre-set Model 5 wrenches are available in three versions with scales: 1 - 5 Nm; 10 - 50 lbf.in; or 10-50 kgf.cm.
