Pokayoke

Tohnichi’s pokayoke (error-proofing) torque wrenches come in a variety of models, including • LS models that control the number of tightening operations, to prevent missed tightening • FH models that transmit tightened-to-completion signals wirelessly • BL solar powered models that eliminate the need for batteries • Marking models that automatically mark bolt heads when set torque is achieved, to provide evidence of proper tightening • CSPLD models that transfer tightening torque data over a cable
