Tool set Gedore R58900050

The Gedore R58900050 tool set is centred on an adjustable torque wrench engineered for controlled screw tightening from 5 to 550 N·m. The set combines a precision torque wrench with a factory test certificate and clear operating instructions. Its integrated ratchet-head function and push-through square allow clockwise and anti-clockwise tightening after switching the mushroom head. The tool is designed for repetition-accurate torque application and audible/tactile torque triggering, making it suitable for demanding workshop and maintenance tasks.

Advantages

The torque wrench offers a wide torque range and a working accuracy of ±3% relative to the set torque, enabling precise and reliable fastening. The wrench features an easy-to-read scale with a magnifying glass and a 1/10 scale for fine settings; the set value is fixed by a lock at the end of the handle to prevent accidental changes. The square drive with integrated ratchet mechanism and the ergonomic handle provide comfortable handling during repeated use. The included test certificate according to DIN EN ISO 6789 documents calibration and traceability.

Suitable for

• Automotive assembly and repair where accurate torque is required
• Industrial maintenance and machine servicing
• Bicycle and motorcycle workshop torque-sensitive fastenings
• Professional trades and precision mechanical assembly
• Quality-controlled tightening in production environments

• Delivery: torque wrench with test certificate and operating instructions

How to use

Select the required torque within the 5–550 N·m range by turning the handle until the desired value aligns with the scale. Use the magnifying glass and 1/10 scale for fine adjustment. Lock the set value by engaging the handle-end lock to secure the setting. Position the square drive on the fastener, set the ratchet direction by switching the mushroom head or using the push-through square as needed, and apply force until the torque wrench emits the audible and tactile trigger indicating the target torque has been reached. For reverse direction tightenings, switch the drive orientation accordingly before use.

Usage recommendations

Use the wrench within its specified torque range and avoid applying impact forces or using extensions that can alter accuracy. Have the torque wrench recalibrated at regular intervals or after any significant shock according to the guidance in the operating instructions and the DIN EN ISO 6789 standard to maintain the ±3% working accuracy. Store the tool with the torque setting returned to the lowest value to relieve spring tension when not in use.
