A torque wrench is a tool used to precisely measure and control amount of torque, or rotational force, applied to a nut or bolt as it is being tightened. Knowing which type of torque wrench is best suited for a particular application is important, as it ensures that correct amount of torque is applied and highest level of safety is maintained.
When it comes to selecting right torque wrench for a job, there are a few factors to consider. The first is type of wrench, as there are several different types available. A common type is a click wrench, which has a sliding scale and a click sound when desired torque has been reached. Another type is a beam-style torque wrench, which has a beam-like indicator and provides an audible beep when desired torque has been reached. Both these types are accurate and easy to use, but for greater accuracy, a dial torque wrench is ideal. This has a dial that shows exact torque being applied, making it perfect choice for delicate jobs.
Another factor to consider is size of wrench. Generally, larger wrench, more torque it can provide, so if a higher torque is required, it’s important to choose a larger model. Also, range of wrench should be assessed – it should be capable of providing torque within range of job being done.
Finally, material of wrench should be taken into account. Steel is most common material used, as it is strong, durable and resistant to rust, but aluminium and plastic can also be used. For more sensitive jobs, it’s best to choose a wrench made of an alloy or a non-metallic material.
Ultimately, answer to question ‘what torque wrench do I need?’ depends on job being done and precision required. Knowing type, size and material of wrench, as well as range of torque, will help ensure that right wrench is chosen for job.
