Torque wrenches come in two varieties: click type and direct reading. The click-type torque wrenches are used mostly for tightening. When the set torque is achieved a “click” sound indicates that it is tightened to completion. The direct-reading torque wrenches are used mostly for measuring and inspection; they display measurement values. Pokayoke (error-proofing) torque wrenches help prevent human tightening errors. They come in three varieties: wired, wireless, and marking. The click type and direct-reading type both have models that transfer measurement results wirelessly.
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.
Tohnichi offers an excellent lineup of direct-reading torque wrenches, including digital, dial, and beam types. The direct-reading torque wrenches include many interchangeable head types. Our selection of interchangeable heads, the best in the world, is designed to promote an extremely high level of workability. The digital type can measure angle in addition to torque, and includes models that can perform advanced pass/fail judgments, and torque wrenches with wireless transmission functions.
