A Torque Wrench is an extremely helpful and very often vitally accurate piece of equipment for any skilled workman, engineer or contractor used to precisely apply a specific torque to a fastener such as a bolt or a nut. It is usually shaped in the form of a socket wrench, however, it is more advanced having special mechanisms internally which measure when the fastener has reached the correct limit. A Torque Wrench allows the user to measure the torque applied to the fastener so it can be matched to the specifications for a particular application making sure they are not too loose or too tight that they break or split prematurely.

The accuracy of a Torque Wrench is vital for the correct application of tightening/torque being applied to a nut, bolt or fastener. Under tightening can and will lead to insufficient thread loading making the tightened object unsecured while over tightening will stretch the nut or bolt beyond its ability to recover causing possible weakening and premature failure. Torque wrenches and all torque tools go out of calibration the more they are used and therefore must be checked periodically to maintain accuracy and to check for wear or defective parts. This testing highlights any potential problems and enables them to be fixed before they cause a serious issue.

The testing also guarantees the operator repeatable accuracy and makes sure they adhere to international standards and is important for companies to ensure that their engineers and mechanics’ equipment safety, reliability and quality of work aren’t compromised.

Calmet offers a full range of calibration and repair services for torque wrenches and torque measuring equipment. Our calibration equipment is traceable to National Physical Laboratory (NPL) and our measurement uncertainty capability is of the highest order. In addition, Calmet has the capability to repair and adjust a wide variety of instruments with an extensive stock of spares required to carry out the work.
