Klikmomentnøgle HAZET 5108-3CT

The HAZET 5108-3CT 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 and robust design made in Germany, it is built for rough workshop use and a wide range of controlled screw-tightening tasks in tyre service, bicycles, passenger cars, commercial vehicles and various industrial applications. The wrench features a palpable and audible safe torque release, a high-contrast laser-marked scale and a calibration certificate with serial number, ensuring traceable accuracy for professional use.

Advantages

The tool offers precise torque delivery with accuracy ±3% of the scale value in the direction of actuation (release accuracy tolerance for model 5107-3 CT ±4%). An integrated shift lever with a free-running function (models 5121-3 CT – 5145-3 CT) reduces the risk of injury and malfunction. A slip-protected handle and improved grip enable easier power transmission, while an optimised sealing ring and repairable ratchet design extend service life. The triangular rotary assembly prevents uncontrolled rolling and provides a latching locking function to secure set torque values.

Suitable for

• Tire service and wheel fastening
• Bicycle maintenance and assembly
• Passenger car and light commercial vehicle repairs
• General trade and industrial screw-tightening tasks requiring controlled torque

How to use

Set the desired torque value by turning the handle until the detent points indicate the required setting; the latching rotary assembly locks the value to prevent unintentional changes. Attach the appropriate 1/4" socket to the square drive, apply steady force until the wrench emits a palpable and audible click indicating the set torque has been reached, then stop applying force. Use the integrated shift lever to change ratchet direction or engage the free-running function where applicable.

Recommendations

Store the torque wrench in its Hexa plastic box when not in use. For long-term accuracy, avoid repeatedly returning the setting to the smallest scale value and arrange regular calibration checks as specified by DIN EN ISO 6789-2:2017. Clean and protect the sealing ring from debris and replace the ratchet repair set if wear reduces performance.
