Calibrating Torque Screwdrivers

To calibrate torque screwdrivers either use a torque tester or torque sensor within the range of the torque screwdriver. For torque screwdrivers calibrate torque in "Peak" mode with a torque tester or torque sensor. Make sure to apply the torque slowly and smoothly.

1. Select a torque tester or torque sensor that covers the torque range of the Micro Torque screwdriver. Connect screwdriver to the torque tester or torque sensor using the appropriate adapters as needed.

2. Apply torque clockwise slowly until screwdriver 'slips' and note reading.

3. Adjust screwdriver to required torque setting as described below.

4. Test and repeat adjustment as necessary to obtain desired value.

5. Recalibrate torque screwdriver at prescribed intervals.

Insert hex key

Adjusting Torque Setting (During Calibration)

1. Remove end cap from screwdriver and insert hex key.

2. Turn hex key clockwise to increase torque and counter clockwise to decrease torque. Do not adjust torque above or below the recommended torque ranges.

MT6, 9, 50 & 80 models are supplied with a T-Bar

1. Snap T-Bar into the slot located in the grip.

Setting and Applying Torque

1. Set desired torque on the scale. Pull down on the "Adjustment Ring" and turn handle clockwise to increase torque and counter clockwise to decrease torque on the scale. Align the desired torque value on the micrometer scale. Release

"Adjustment Ring."

2. Tighten nut or bolt by applying steady twists. Screwdriver should be kept at 90 degrees to axis of bolt during tightening. When pre-set torque is reached, the screwdriver will 'slip.'

3. The screwdriver will automatically reset itself for the next application.

4. With its unique cam-over design, it's impossible to over tighten beyond the preset load.

Micro Torque Screwdriver Operating Instructions

Rev 3.3 (3/23/2017)

Maintenance Schedule

Like an automobile, torque screwdrivers contain moving parts that require periodic servicing and lubrication.

Expected Tool Life

With normal use – 100,000 operations

Period between Resetting of Torque

5000 operations (as recommended in BS EN 26789:1994). It is acknowledged that some tools achieve 5000 operations in a relatively short period of time. Under these circumstances the user may decide, with the benefit of their experience, to increase the period between calibration checks.

Routine Maintenance

After 100,000 operations, strip, clean & re-grease the Spindle, Cam & Roller. Any worn components should be replaced.

Note: Any tool that is dismantled during its life must be re-lubricated in accordance with the Mountz recommendations. Do not clean tools by immersing them in solvent, as this will destroy the internal lubrication and cause failure of the tool.

Testing & Servicing

Torque tools go out of calibration with use. Calibrating a torque tool is a finetuning process of bringing the tool back within its tolerance. Regular torque calibration of a hand screwdriver ensures accuracy, repeatable tool performance, and adherence to international standards.

We recommend a general once a year calibration interval. However, it is the user’s organization that must determine suitable intervals based upon equipment performance, application, degree of usage and management objectives.
