Now that we have explained what torque is and how the method of measuring torque came into existence, we will delve into the history of the torque wrench.A flat wrench with a circular hole and two inward protruding pins to engage slots in the nut. This type of nut is used on bicycles to secure the front fork pivot bearing to the headpiece of the frame. So that an operator knows how much torque is being applied, wrenching tools tend to have a screen or an easy-to-read scale to display the tightness levels of a nut/bolt. Alternatively, there are preset torque wrenches, which allow the torque to be set by an individual and then the tool can be used freely by many people on a manufacturing line.

Higher quality wrenches are typically made from chromium- vanadium alloy tool steels and are often drop-forged. They are frequently chrome-plated to resist corrosion and for ease of cleaning. To make sure torque wrenches provide reliable and precise measurements, they should be regularly calibrated. Before you carry out any car maintenance, ensure that you thoroughly understand the vehicle’s requirements as specified by the manufacturer. Torque wrenches provide a specific amount of torque for fastening purposes. This helps in avoiding over-tightening of the nut-bolt assembly. Calibrating the wrench will provide the required amount of torque. If your wrench isn’t calibrated correctly, then you are highly at risk of over-tightening or under-tightening a nut or bolt, which may affect the performance of your equipment or create a health and safety hazard.
