Torque Testers and Torque Analyzers are used as a quality control devices to test or calibrate torque controlled tools. This includes electronic torque wrenches, click torque wrenches, dial torque wrenches, electric screwdrivers, air screwdrivers, pulse tools, cordless screwdrivers, nutrunners, and torque screwdrivers, engine, crankshaft, gearbox, transmission, motor, rotor, bicycle crank, etc. Today’s advanced Torque Testers and Torque Analyzers include the ability to measure in clockwise and counter-clockwise directions, available in handheld portable size, LCD digital display, torque units converter, digital memory for torque measurement data storage, and wired/wireless PC computer interface with torque analysis software.

Controlling torque is essential for companies to ensure their product’s quality, safety and reliability isn’t compromised. The failure of a three-cent fastener that isn’t properly tightened can lead to catastrophic or latent failures. Fasteners that are insufficiently torqued can vibrate loose and excessive torque can strip threaded fasteners. Using a quality torque tester has become increasingly important for many companies to ensure that proper torque is being applied and maintains gauge requirements associated with the ISO 9001 Quality Standard.

Torque measurement has become an integral part of using electric and pneumatic tools to install threaded fasteners. Testing a tool before using it on the line will tell engineers if the tool can do the job if all other variables are in control. Torque testing can give manufacturers a good idea of how well their tools can perform. Assemblers routinely test tools for accuracy and repeatability before using them on the line and after making repairs or adjustments. Many assemblers test new tools before buying them.

Assemblers measure torque during fastening to ensure process capability. “In-process” torque monitoring can identify problems with extensions, sockets, methods and access to the joint. It can also indicate when preventive maintenance is needed. Quality engineers perform torque audits on finished products prior to shipping. This is the last chance to catch loose fasteners and short-term relaxation in the joint.
