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.
Adjustable Torque Wrench
This lineup of wrenches equipped with a torque scale includes a ratchet function, metal handles with a knurled finish grip, and interchangeable head types. The QL/QLE2 series accommodates a wide range of bolts, from M4 to M42. The YCL2 series is equipped with Tohnichi’s exclusive Two-Step Motion system to prevent over-torque.
Pre-lock Torque Wrench
These pre-lock torque wrenches effectively prevent users from mistakenly changing the torque. They are equipped with a torque scale but to change the set torque a tool is required, making inadvertent changes to set torque difficult during a tightening operation. This effectively prevents human errors. There are pre-lock torque wrenches with a ratchet function and pre-lock torque wrenches that use interchangeable heads.
Preset Torque Wrench
Preset torque wrenches without a torque scale. Suitable for repeated tightening operations using the same torque value. This lineup includes a ratchet, interchangeable heads, spanner heads, ring heads, and a rotary slip that prevents over-torquing.
Pokayoke Torque Wrench
These Pokayoke (error proofing) torque wrenches are designed to prevent human tightening errors. The lineup includes wired LS type torque wrench using tightening count control to prevent human tightening errors, wireless FH type that transmits tightened-to-completion signals, BL type that uses solar power instead of batteries, the CSPFHW series that prevents double tightening, marking type that automatically leaves a mark on the bolt head to show the bolt is tightened-to-completion as soon as the tightening operation is completed, and the wired CSPLD that transmits tightening torque data. You can, on your own, upgrade the wired LS type torque wrench to a wireless Pokayoke (error proofing) torque wrench by removing the LS module and replacing it with the compact T-FHLS transmitter.
Angle Wrench
Angle wrenches for rotation angle tightening. An LS type torque wrench can be equipped with an M-DW angle display module to convert it into an angle wrench. Examples are DWQL and the digital angle wrench CTA2.
Wireless Data Transfer Torque Wrench
These torque wrenches emit a “click” sound when the set torque is achieved and, at the same time, wirelessly transmit tightening torque data. The FDD model is equipped with double tightening detection, while the FDD-AD improves tightening reliability by performing advanced pass/fail judgments based on torque and angle. The CSPBTLD transmits tightening torque and angle data wirelessly to a Windows or iOS device, and can input data to Excel and link to a computerized ledger system.
