Why is this important?

• A short release distance improves control and is particularly advantageous in confined installation spaces.

Short-travel torque wrenches (often also known as folding keys) are set in advance to a specific torque value and give an audible and tactile signal when this value is reached. Their close-gap release, with an angular movement of only around 3°, makes them ideal for confined spaces and allows them to be reused quickly after release.

However, the user must accurately perceive the trigger point; otherwise, there is a risk of exceeding the torque setting and damaging components or the tool: the lower the torque, the weaker the palpable and Audible signal becomes.

The close-gap release mechanism supports controlled force transmission by clearly signalling the moment the set torque is reached. This enables precise, reproducible tightening of screws. This type of trigger mechanism is therefore particularly sought after in applications where accuracy and immediate feedback are crucial to the quality of the screw connection.

Important:

• The exact dimensions of the tip cube are crucial for the accuracy of the trigger mechanism

By the way:

• The characteristic clicking sound when the set torque value is reached is a popular running joke amongst new workshop users: if the clicking sound fails to occur, they are sent off to fetch a click cartridge.
• Instead, the trigger mechanism is realised via the tilting element (the tip cube), as can be seen in the diagram below.
