DESCRIPTION: Also referred to as a "click" wrench, these are the most popular type of mechanical torque wrench. An internal spring is tightened by turning the handle. The spring pushes against a block, and both are calibrated so the block pivots when the torque setting has been reached. This quick pivoting creates the "click" sound. When the force at the handle is released, the block resets to its original position and is ready for the next torque application.
OPERATION: Set the desired torque value by pulling down on the lock ring while turning the handle. Al- ways
approach torque setting from a lower setting. The tube displays the major torque values, and the lock ring has the
minor torque values. Apply force at the handle until the "click" is felt or heard, and then release force.
ADVANTAGES: Most common type of torque wrench. "Click"felt at the handle indicates torque value reached.
Rugged, durable legacy design.
DISADVANTAGES: After day's use, internal spring pressure must be released by unwinding the handle.
APPLICATION: Highly versatile: any general-purpose torque applications: auto engine, machine maintenance,
construction, oil field, compressor/generator, etc.
