A torque wrench serves the purpose of applying accurate torque on the fasteners. Applying inaccurate torque can either result in imperfect fit or even damage the entire set up. This is a handy tool when you are working with high performance equipment, inspecting tolerances of nuts and bolts, automobile engine and other such parts. Extreme care has to be taken in the operation and maintenance of this tool.
When you have a torque wrench in your kit, have these tips in your head:
Usage:
- Irrespective of the type and magnitude of the hand tools, always protect your eyes by safety goggles while working with them.
- Each such tool is designed to work in a specific range. This helps you to decide the perfect tool for your application. Exceeding this limit can cause considerable damage to your device.
- Don’t use an accessory just because you have it. Stick to the type of accessories the manufacturers specifies.
- Take extreme care so that the tool doesn’t drop on hard surfaces. When you accidentally slip it off, recalibrate the tool before using it.
- While storing the click type wrench, adjust it to the minimum scale position.
- Use the device for the intended purpose. Remember that it is not the primary tool for loosening or tightening nuts or bolts.
- While handling the torque wrench place your hands on the centre of the tool to ensure better maneuvering. If you have to make use of both the hands, place one over the other.
- These tools are so designed that they send out signals like beeping or clicking after reaching specific torque. When the tool shows such indications, cease the operation.
Maintenance:
- Avoid exposing the wrench to extreme working conditions like intense pressure and high temperature.
- Study the torque wrench suppliers’ manual about the device. It helps you to get started and work effectively with the tool. Focus on the aspects like lubricants used, direction of operation, torque pattern, tight/release cycles and others.
- Every time you move out to work, check the tool for damages like cracks or worn out parts. Take immediate action, if you find something wrong with the tool.
- When left unused, there are chances that the tool can be corroded. Clean the tool after every use store in protective casings.
It is essential to know the types of torque wrenches before you choose one. The first aspect to be considered ion this aspect is the accuracy of the system. Make ensure that the tolerance doesn’t exceed 5%. Comparatively better ones have an accuracy of 2%. Focus largely on the quality aspects of the device rather than its fancy features. Never expect the device to perform well just because it has an LED readout. Prefer a well made and sturdily designed wrench. Ask yourself, “How often do you use this wrench?” The answer for this question lets you decide on the amount you can spend on the wrench.
