Chiave dinamometrica HAZET 5107-3CT

The HAZET 5107-3CT is a mechanical click torque wrench with a reversible ratchet and a 1/4" square drive. With a total length of 234 mm, an audible and palpable click indicates when the set torque is reached. The tool is designed for workshop use and comes with a calibration certificate and serial number. The scale is laser-marked for permanent readability and the rotary assembly has a triangular shape to prevent uncontrolled rolling. It is supplied in a sturdy Hexa plastic case and conforms to relevant standards for torque tools.

Advantages

The torque wrench features a user-friendly reversible ratchet and optimised sealing to protect internal parts from debris. A ratchet repair set allows customer self-assembly and extends service life. The handle includes slip protection for improved grip and easier power transmission, while detent points on the adjustment aid provide clear guidance when setting torque. Settings are locked by a latching function on the rotary assembly and lock symbols indicate locking status. Integrated shift lever variants include a free-running function to reduce the risk of injury and malfunction. The product is tested in accordance with DIN EN ISO 6789-2:2017 and delivered with calibration documentation.

How to use

Select the required torque value using the rotary adjustment with detent points, then lock the setting using the latching function on the rotary assembly. Attach suitable sockets to the 1/4" square drive and apply steady force until an audible click and palpable release indicate that the preset torque has been reached. Use the integrated shift lever to change ratchet direction; models with a free-running function allow safer operation during fast engagement. Store the wrench in the supplied Hexa case and observe the calibration certificate and maintenance instructions for continued accuracy.

Recommendations

For reliable results, use clean sockets and avoid sudden impulse loads. Periodically check calibration according to the documented intervals and replace worn sealing elements or assemble the ratchet repair set as needed to maintain safe, long-term operation.
