Wera torque indicator with fixed torque for internal hex screws. Tamper-proof. The robust slip clutch guarantees a clearly audible and tactile release signal upon reaching the set torque, and over-torquing is impossible. The loosening torque is multiple times higher than the set tightening torque, which means that generally no additional tool is required to loosen screw connections. The shape of the handle fits the entire hand well, and the fingers rest comfortably in the softly rounded grip recesses. This ensures optimal, ergonomic power transmission.
