Why does a torque wrench break down? How can you prevent it?

 Torque wrenches come in a variety of designs, from the most basic to the most complex, and they are all used to measure the torque value or the amount of force used to tighten a nut or bolt. Each of them is a bolting tool made to ensure correct fastening and avoid over or under-tightening a bolt. Tightening might make the object you are assembling or attaching structurally weak and even unsafe to use, while overtightening can destroy the fasteners. This is valid for both constructing stationary objects and automobile parts. Here are the reasons why a torque wrench breaks down and how to prevent it. 

Unreliable application research

It is crucial to comprehend the torque tool's application and build a unique solution around it. The application study is crucial to comprehending many elements in order to suggest the best instrument and components to finish the job quickly without experiencing any breakdowns.

Side load

When the tool is fitted to the stud improperly, side load is produced. It frequently happens as a result of inadequate training or poor application research. Although side load may not harm a tool right away, it might cause long-term damage owing to persistent side load. The torque tool housing is damaged by unneeded side loads applied over an extended period of time.

Incorrect alignment of the reaction arm

Every action requires an equal and opposite response, according to Newton's third law. In light of this, a torque wrench requires a reaction arm that would lock at a nearby location while applying torque output. The action axis (torquing axis or bolt axis) and the reaction axis should be parallel and in the same plane as the torque wrench attempts to position itself in this manner.

Improper storage or handling

The instruments are frequently not cleaned after use, which is a common problem brought on by incorrect usage. As debris and dirt from past uses might ultimately wear off the instrument, it is crucial to clean it frequently after use. Another problem dealt with is incorrect handling; technicians frequently pull hoses to lift or adjust fastening tools while they are in use. The swivel post's seals may be harmed as a result. As a safety precaution, we advise using a tool handle to facilitate handling and keep the operator's fingers away from the reaction point or pinch point. Every instrument must have a designated case and designated position for convenient access and storage, which is vital to ensure.

Measures required to safeguard a torque wrench

Scheduled tool maintenance

This is crucial since it comprises calibration and auditing, which assess the tool's condition and go beyond simple repairs. Auditing assists in finding any issues with the instrument so that they can be fixed as soon as possible. Similar to this, torque wrench accuracy is checked during tool calibration. Tools need to be audited and calibrated frequently since aging tools lose accuracy.

Complete tool training

Each operator needs to receive thorough instruction on how to use the tool for any industry. It serves as both a safety precaution and a safeguard against sideload-related tool failure problems. Therefore, by enabling the operator to utilize the bolting tool properly, training lowers maintenance expenses. Training also emphasizes how crucial it is to handle tools carefully to prevent pinch points.

Accurate application research

A correct application study can resolve up to 40% of tool breakdown cases, as mentioned in the section on the effects of a poor application study. Before suggesting a tool to a client, every site engineer should be familiar with the programme. A wrong tool recommendation might cost the customer much because it can harm both the tool and the application.

There isn't necessarily a pattern to tool damage. Your operators should closely monitor the tools themselves in addition to doing routine inspections to spot any damage or malfunction and report it. Tools with inconsistent torque, broken mechanisms, or evident physical damage like gouges, chips, cracks, or deformities should be taken out of service and marked for repair. Additionally, over time, tools will inevitably become out of calibration, so it's imperative to keep a regular calibration schedule.

It may be preferable to work with a damaged or broken tool than to let a line go dark for a while. Of course, having backup gear on hand is always a good idea in case something goes wrong.

Damaged or broken torque tools are less common with the correct preventative maintenance routine and a watchful eye. It's a good idea to have replacement equipment on hand in case an accident occurs to reduce downtime.

Conclusion

So, these are the reasons why a torque wrench may break down and the solutions to how it can be prevented. Durable torque tools are made well. Unplanned downtime can be reduced with regular tool maintenance. The manuals that come with your torque equipment will contain maintenance tips as well as usage guidelines.
