Wera 400 Torque Hex Screwdriver Item # 850689
Description
Wera torque indicator with fixed torque for hexagon 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 important information is indicated on the tool
The handle is marked with an indicative screw symbol, size, torque and maximum release torque.
Hex-Plus
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 hexagon socket screw!
Torque-indicator with pre-set and tamperproof torque value
Torque-indicators
Suitable for applications requiring a non-adjustable i.e. a tamperproof torque blade assembly.
Excess-load signal
Distinctly audible and noticeable excess-load signal when the pre-set torque is reached.
Ergonomic design
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.
Multi-component handle
Multi-component screwdriver handle for ergonomic working.
Features:
- T-handle is ideal for transferring controlled tightening torque and high loosening torque
- Error-free screwdriving due to non-slip friction clutch and exact torque transmission
- Tamper-proof against accidental changing of set torque value
- Particularly corrosion resistant blade
