Wera Safe Torque A1 1/4" Torque Wrench

The Wera Safe-Torque A 1 is a precision 1/4" drive torque wrench designed to prevent overtightening through its slip-over release mechanism — making it an essential tool for any application where accurate torque is critical.

Once the set torque value is reached, the slide-over mechanism disengages automatically, ensuring the correct torque is applied every time without risk of exceeding it. The setting range of 2 to 12 Nm supports both clockwise and counterclockwise operation, making it equally suited to tightening and controlled loosening tasks.

Setting the desired torque is straightforward, with audible and tactile clicks at each scale value providing clear, reliable confirmation. This makes the wrench particularly well suited for applications in automotive work, bicycle maintenance, and precision assembly where consistent, repeatable torque values are essential.

The Torque Lock function allows the torque mechanism to be deactivated entirely, converting the tool into a standard ratchet capable of high loosening moments and angle-of-rotation applications. With 72-tooth fine toothing delivering a return angle of just 5°, the wrench performs reliably in confined spaces where swing arc is limited. The release angle after target torque is reached is only 30°, minimising the risk of accidental over-application.

Features and Benefits:
• Slip-over release mechanism prevents overtightening once target torque is reached
