The Relationship between Interchangeable Heads and Torque Wrenches ?
Tohnichi?s interchangeable head wrenches have speci?c diameter round Nominal diameter
ends that ?t into corresponding head base openings. Head and wrench ? CL100N×15D
model names include the diameter sizes so heads can be matched to
wrenches that will accept those heads.
For example: SH15D×17 will ?t on CL100N×15D ? Nominal diameter
A variety of different head types (SH, RH, QH, RQH, FH, DH, AH and SH- 15D=?15
N) can be used on one wrench or different types of wrenches such as CL (for ?
tightening) and CEM3 (for inspection) can use the same head that has the SH15D×17
corresponding diameter size.
RH Ring Head

RoHS C Width

1
The RH type ring heads guarantee the safe work as the axes of bolt and RH ring
head are always aligned and prevent the heads will drop.

Note: RH8D×5.5 to RH8D×7 are hex shape.
