Quality & Accuracy
Special alloy steel, precision manufacturing, special heat treatment, advanced design and the individual inspection of each product at various stages of production are the foundations of Torque Master quality.
±3% accuracy, better than the ±4% required by ISO 6789:2017
ISO 6789:2017 is the international standard for hand torque tools. Full-load tests are carried out on each and every torque wrench before dispatch.
A three-phase signal (sight, touch and sound) tells the user the set torque has been reached, and torque can be applied to both right-hand and left-hand threaded fasteners. TMT micrometer wrenches are calibrated in the clockwise direction only.
Durability has been a priority throughout development, both in the life of the tool and in its calibration.
From steel to dispatch
Special alloy steel
High-strength alloy steel is used for torque wrenches, sockets and drive tools.
Precision manufacturing
Sockets are machined to maintain the tolerances recommended for impact application on hex and square drives.
Special heat treatment
Precise heat treatment gives torque wrenches their strength; sockets are multiple tempered to keep hardness within limits.
Stage-wise inspection
Each product is individually inspected at various stages of production.
Full-load testing
Full-load tests are carried out on each and every torque wrench before dispatch.
ISO 9001:2015
Torque Master operates an ISO 9001:2015 certified quality management system.
Calibration & recalibration
Every Torque Master torque wrench carries its own unique serial number and is supplied with its own calibration certificate. Calibration is traceable through NABL-accredited reference equipment.
Recalibration interval
The recalibration interval is set by the user, based on the required accuracy, frequency of use, typical load, and the operating and storage conditions. If you do not have a control procedure, use a default interval of 12 months or approximately 5,000 cycles. For the first recalibration, the interval is counted from the date of first use, not from the factory calibration date.
Recalibrate immediately
- After an overload greater than 125% of the maximum rated load
- After any repair
- After any mishandling, such as a drop, that could affect its accuracy
A full repair and calibration service is available on request, at a charge. Please do not attempt to adjust or repair a torque wrench yourself.
Warranty
Torque Master torque wrenches carry a warranty of 12 months from the date of purchase.
- If inspection shows that a fault is due to defective materials or workmanship, the repair is carried out free of charge.
- The warranty is effective only on production of the original dated purchase invoice as proof of purchase within the warranty period.
- The warranty does not cover normal wear and tear, or any damage caused by misuse, careless or unsafe handling, alterations, accidents, or repairs attempted or made by anyone other than the authorised service department.
- If a tool is found to be outside the terms of the warranty, a written quotation for the work required will be provided.
- This warranty applies in place of any other warranty, express or implied, and variations of its terms are not authorised.
Calibration and warranty
Calibration validity is independent of the product warranty period. The calibration interval is determined by the user and starts from the date of first use, not from the factory calibration date, so a calibration certificate is not considered expired solely because the warranty period has ended.
For warranty or after-sales service, contact Torque Master directly or your authorised dealer.
Certificates & awards
Torque Master is ISO 9001:2015 certified and received the Industry Outlook Excellence Award for top 10 industrial hand tools manufacturers.
