## Summary description

The HAZET 5121-3CT is a mechanical click torque wrench with a 1/2" square drive and a length of 421 mm. It offers precise torque measurement, ensuring accurate fastening of bolts and nuts. Ideal for automotive and industrial applications, this tool is designed for durability and ease of use, making it a reliable choice for professionals.

## Long description

The HAZET 5121-3CT is a mechanical click torque wrench with a reversible ratchet and a 1/2" (12.5 mm) square drive. With a total length of 421 mm and a laser-marked scale, it provides precise torque setting and permanent readability. The tool is designed for demanding workshop use and delivered in a sturdy Hexa plastic box with calibration certificate and serial number. It complies with DIN EN ISO 6789-2:2017 and is made in Germany.
Advantages
The reversible ratchet offers safe torque release that is both palpable (close gap release) and audible (click sound). Accuracy is ±3% of scale value in the direction of actuation (model 5107-3 CT has ±4% release tolerance). The wrench includes an optimised sealing ring to protect against debris, a ratchet repair set for customer self-assembly, and a handle with slip protection for improved grip. An adjustment aid with detent points and a latching locking function secure the selected torque value. The triangular rotary assembly prevents uncontrolled rolling and provides openings for cable-loop attachment. Integrated shift lever models (5121-3 CT – 5145-3 CT) include a free-running function to reduce risk of injury and malfunction. Long-term tests on related HAZET series indicate no need to return the wrench to the smallest scale value after use.
Suitable for
Tire service and bicycle maintenance
Passenger car and commercial vehicle fastening tasks
Controlled screw tightening in trade and industry

How to use
Set the desired torque by turning the handle until the detent points align with the scale and the rotary assembly latches the value. Attach the appropriate socket to the 1/2" square drive and position the wrench on the fastener.
