ADS - EDS: Torque Wrenches - Direct Reading and Dial

Dial wrenches are typically used as a quality control instrument to verify or monitor torque. However, some customers find them a resourceful production tool. In all cases, Mountz dial wrenches are found to offer unmatched performance for several reasons. First, they are simple and easy to calibrate. Second, they incorporate an overload protection device to prevent over-torque and damage to parts or to the wrench. Third, Mountz dial wrenches are non length dependent, which means one can hold the wrench anywhere along the handle and exact torque will be achieved. Lastly, the wrench offers a ratchet so that engagement to the work piece is simple and precise.

Mountz Tables

  • - The preferred and certified ranges of these tools is in accordance with the requirements of ISO 6789:1992.
  • - Non-length dependent.
  • - Dual scale in American and S.I. units. Single scale models are available upon request.
  • - Quality constructed for accuracy and reliability with an attractive abrasive resistant finish for longer life and ease in identification.
  • - Mechanical stop provides overload protection to 125% of full scale.
  • - Fine main and memory pointers provide accurate readings.
  • - Lightweight aluminum handle (w/non-slip grip) for improved balance. Scuff-resistant non-slip finish.
  • - Standard double-ended spindle ratchet mechanism allows for left handed torque applications
  • - Single-end spindles available upon request..
  • - Exclusive built-in ratchet mechanism.
  • - Recessed dial minimizes dial breakage.
  • - Torque indicating signal light - standard on CDS, DDS and EDS models. Optional on certain ADS and BDS models.
  • - All models labeled for instant identification of serial number for traceability.


ADS and BDS models are supplied with a protective case.

EDS models are available with single and double-end, but are not available with a ratchet end.

For single-end spindle specify SE after model name. Example ADS4-SE All light Signal Wrenches use standard size batteries.

All ADS–EDS wrenches are available in single scale models

Extension Spanners

Special extension spanners are available upon request. When ordering, please provide the following information:

A) Square Drive Size

B) Size of spanner end

C) End type - Box, Open or Flared

E) Center distance between the square drive and the spanner end fitting

T) Maximum torque to be applied

Open End
Flared End Box End

Note: Due to the low torque ranges and high accuracy, it is recommended that Models ADS4 & ADS8 should not be used with Extension Spanners.

Extension Adapters

Adapters offer alternative solution for overcoming space and access limitations and are availabe upon request.

1. Place the end fitting to the extension adapter.

2. Then attach to the wrench's square drive.

3. Measure and note distance ``E" from the center of the end fitting to the wrench square drive.

Note: Extension Adapters cannot be used with the ADS4, ADS8, ADS12D.
*Please note that when using extension spanners or adapters, the torque applied to the fastener is greater than that shown on the torque wrench dial.
