Click torque wrench HAZET 5120-3CT

The HAZET 5120-3CT is a mechanical click torque wrench with a reversible ratchet and a 1/4" (6.3 mm) square drive. With a total length of 234 mm, it delivers precise torque control for fastening bolts and nuts in automotive, bicycle and tyre service applications. The tool is designed for robust workshop use and is supplied in a sturdy Hexa plastic box with a calibration certificate and serial number.

Advantages

The torque wrench offers a palpable and audible safe torque release with an accuracy of ±3% of the scale value in the direction of actuation (5107-3 CT ±4% release accuracy tolerance). It features an optimised sealing ring to protect against debris, a ratchet repair set for user self-assembly, and a handle with slip protection for improved grip. An easy-to-read, high-contrast laser-marked scale ensures permanent readability. The rotary assembly has a latching function for secure locking of set values and a triangular shape to prevent uncontrolled rolling. Integrated shift lever and, on models 5121-3 CT to 5145-3 CT, a free-running function reduce the risk of injury and malfunction.

Suitable for

• Tyre service and tyre pressure control systems
• Motorcycle and bicycle maintenance

How to use

Select the required torque value by turning the handle until the detent points align with the desired setting; the detents aid quick and safe adjustment. Lock the value using the latching function on the rotary assembly and attach the correct socket to the 1/4" square drive. Apply torque in the intended direction; the wrench will release with a palpable and audible "click" when the preset torque is reached. After use, store the tool in its Hexa box and keep the calibration certificate for traceability.

Usage recommendations

Have the torque wrench regularly inspected and recalibrated according to DIN EN ISO 6789-2:2017 intervals; avoid turning the setting back to the smallest scale value unnecessarily and protect the tool from heavy contamination to ensure long-term accuracy and reliability.
