FIELD: mechanical engineering. ^ SUBSTANCE: torque wrench comprises head connected with the handle whose internal space receives the adjusting screw. The head is mounted for permitting axial movement inside the pressure-tight casing. An elastomeric material is interposed between the head and casing and interacts with the piston mounted inside the hollow handle and connected with the adjusting screw. The end of the piston most distant from the head is provided with a scale whose readings are taken with respect to the face of the handle. ^ EFFECT: smoothed control of torque. ^ 2 dwg
