Description
TOHNICHI Open Spanner Head 12D 11–17mm
An interchangeable head for a Tohnichi CL/CSP/CDB-series torque wrench. The wrench body holds the mechanism and the calibration; the head decides what it grips, so one body covers open-end, ring, hex and hook work by swapping the head.

- Changing head length changes the effective lever, so the wrench needs re-setting
- Sold separately from the wrench body
