A100N [Overall length 340 mm]

A180N [Overall length 489.5 mm]

Replaces conventional two-step tightening process with one tool in great efficiency.
Provisional tightening is applied using the air motor operation, and completed in high accuracy by manual torque wrench operation.
Accuracy improved with final tightening completed by manual torque wrench work.
Changing tightening torque is easy with the N･m unit scale.
Easy calibration with torque wrench tester.
L version comes with limit switch. LS version available with limit switch, which creates error-proofing (Pokayoke) system when used with CNA-4mk3 count checker (sold separately).
Applicable for international use including the EU region.
