WERA torque screwdriver "400 Hex torque indicator"

Sliding T-handle, inside hexagon, fixed torque value, tamper-proof, Hex-Plus profile
Error-free screw fitting thanks to non-overtightening slipping clutch and exact torque transmission. The robust slip clutch guarantees a clearly audible and perceptible release signal when the set torque is reached and it is impossible to overtighten the torque. Release torque is several times higher than the set tightening torque, meaning that for the most part no additional tools are required to loosen screw connections. The shape of the grip fills the entire hand well and the grips lie in the softly rounded recesses. This ensures optimum, ergonomic power transmission. Hex-Plus tools have larger contact surfaces to protect the screw head.
