Mechanical

Mechanical torque tools apply a controlled tightening force without electronics, using a spring or beam mechanism that is inherently robust.

Tohnichi supplies this range. Click type wrenches signal the setpoint audibly and are the standard for production assembly, while beam type wrenches show torque continuously on a scale and cannot be preset, which makes them useful as a check tool. Match the torque range so working values sit in the middle of the span, since accuracy degrades at the extremes of any mechanical wrench. Confirm the drive size and whether interchangeable heads are required. All mechanical wrenches need periodic recalibration.
