majority of operators who will work there. This can reduce future costs arising from work-related health disorders among operators, along with costs arising from poor product quality. Also, the need to redesign the production system later may be avoided A wide variety of tools are available to control and measure the amount of torque applied to fasteners. These "torque control tools" utilize calibrated torque setting mechanisms that may be factory pre-set, or user-definable. When the specified torque setting is reached, the tool provides a visual, audible, or tactile signal. For low production applications, or to verify torque out in the field, manual torque wrenches are available that may have dial indicators, emit an audible click, or slip when the specified torque value is achieved. Manual screwdrivers work on the same principle by providing a slipping sensation when the specified torque is reached. Electric or pneumatic screwdrivers can be incorporated into workstations to speed up production and reduce repetitive motion injuries and carpal tunnel syndrome.
For large fasteners in industrial applications, manual and powered torque multipliers are often used to replace impact wrenches. Torque multipliers are available that can deliver over 30,000 ft. pounds of torque, with precision.
Another variable to be considered is whether torque will be applied statically or dynamically. Static torque is applied by hand and occurs relatively slowly. Dynamic torque is applied with a power tool at a high rate of speed. More tension is normally generated by dynamic torque than static at a given torque setting, because of the momentum generated by the tool's motor and gear assembly (inertia) and the lower coefficient of friction.
Varying loads and vibrations represent a special challenge for threaded fasteners. Since a properly torqued threaded fastener is always under steady tension in connecting two
