400 Hex Unclog

The most important instructions are engraved on the tool itself.

The handle has the corresponding markings, such as the screw symbol, size and torque, as well as the maximum loosening torque.

Hex-Plus

Internal hex screws are problematic because the bearing surfaces through which the tool's force is transmitted to the screw are extremely narrow. This can damage the screw head. Hex-Plus tools have larger bearing surfaces that prevent this type of damage. And it's worth remembering: Hex-Plus tools fit any standard hex screw!

The "T" handle is ideal for transmitting controlled tightening torques as well as high loosening torques.

The work on bolted joints is error-free thanks to the limited friction coupling that cannot be exceeded, as well as the precise transmission of the turning torque.

Protected against tampering with the preset tightening value

A rod that is especially resistant to corrosion

Unclogging with fixed torque and protected against tampering

Preset, adjustable torque screwdrivers

For application cases with the rod unit and non-modifiable tightening torque, i.e., non-manipulatory.

Audible and tactile signals

The "click" can be clearly heard and felt as soon as the set tightening torque is reached.

Ergonomic shape

The ergonomic T-shaped handle fits comfortably in the palm of your hand. Your fingers rest in the gently rounded grooves of the handle. This ensures that your entire hand is in contact with the handle, minimizing friction between your hand and the handle.

Multi-component handle

The screwdriver handle is of a multi-component structure that allows for ergonomically correct work.

Item description

Wera "loosening" tool with fixed tightening value for internal hex screws. Tamper-proof. The robust friction coupling emits a clearly audible and palpable click when the preset torque is reached. Overtightening beyond the set torque is now impossible. The loosening torque is always greater than the set tightening torque. This means that in most cases, no additional tools are needed to loosen screw connections. The handle of this tool is designed to fit comfortably in the hand, with the fingers resting gently within the rounded contours. This ensures optimal and ergonomic power transmission.
