The Tohnichi torque wrench is classified into two categories; click type and indicating type. Click type is mainly used for a tightening work in which “click” notices reach of set torque value. Indicating type is mainly used for a measurement or inspection work in which a measured value expresses numerically.

There are two types of torque screwdrivers: signal-type and direct reading models. Click type torque screwdrivers are used primarily for tightening. When the set torque is achieved, rotary slip prevents over-torque, and the hand feels a release of tension, indicating tightened-to-completion. Direct reading torque screwdrivers are used primarily for measuring and inspection. They display numerical measurement values. We also supply Pokayoke (error-proof) torque screwdrivers designed to prevent human tightening errors.
Click Type Torque Wrench
Tohnichi’s lineup of click type torque wrenches includes adjustable types with torque scale, prelock types that have a torque scale but also help prevent human error by making it difficult to change torque value, preset types without a torque scale that are designed for repeated tightening at the same torque, Pokayoke (error-proofing) torque wrenches that help prevent missed tightening, angle wrenches for rotation angle tightening, and types that, in addition to their click function, transmit tightening torque data wirelessly.
