STAHLWILLE Rotational Angle Measuring Head 3mm

- Removable magnet for attaching sockets with 1/2 internal square drive;
- The tenon of the rotational angle measuring head is attached to the insert head of the torque wrench No 730 (size 12, 20 or 40);
- This turns the torque wrench into an angle-controlled wrench which is first used to torqueup to the preset snug where the signal indicates that the preset has been attained, and then, after the rotational angle measuring head has been reset to zero, further force is applied until the required angle has been reached;
- The function of the wrench insert head remains unchanged;
- A range of insert tools can be used;
- The magnetic foot of the flexible reference arm has a universal joint mounting and can be attached at any suitable angle;
- Additionally, a signal emitter (No 7390) can be attached tothe rotational angle measuring head and the red light will light up when the rotational angle measuring head, which has been set tothe required angle, returns to zero during tightening.
