WERA 05005080001 400 HEX 4.0MM/4.0 NM

Wera® Torque Screwdriver, Series: 400 Hex, Measurement System: Metric, 4 mm Drive, 108 mm Overall Length, 4 N-m Maximum, Steel

Wera® torque indicator with fixed torque for hex sockets. Tamper proof. The robust slip clutch guarantees a clearly audible and tactile trigger signal when the set torque value is reached and it is therefore impossible to apply any further torque. The loosening torque is significantly higher than the set tightening torque, therefore no additional tools are needed for loosening screw connections. The shape of the handle fills the whole hand well and the fingers lie in the softly rounded recessed grips. This ensures optimal, ergonomic power transmission. The ergonomic design of the T-handle fills the palm of the hand. The fingers rest in the soft, rounded recess and the whole hand is in contact with the handle - so there is no friction loss between the hand and handle. Hexagon socket screws are a problem, because the contact surfaces that transfer the force of the tool to the screw are very narrow. The consequence: the head of the screw can be damaged, usually rounding out the recess. Hex-Plus tools have larger contact surfaces to prevent this, driving from the flats of the recess, rather than the corners. Good to know: Hex-Plus tools fit into every standard hex socket screw.
