Torque wrench Tvardy 3/8" drive, 19–110 Nm, professional model T00021

Professional torque wrench Tvardy 3/8" drive, 19–110 Nm, professional model T00021 is a mechanical, adjustable hand tool intended for controlled tightening of bolts and fasteners. The tool provides a torque range of 19 to 110 Nm with a 3/8" square drive, suitable for workshop, automotive and assembly environments. Its adjustable scale and audible click mechanism allow the user to set and maintain a target torque value, reducing the risk of over- or under-tightening and supporting consistent joint integrity during maintenance and repair operations.

Advantages

The torque wrench offers a wide working range (19–110 Nm) in a compact 3/8" drive format, combining precision adjustment with portability for service and workshop use. The mechanical design with a presettable torque stop and click indication enables repeatable results without electronic components, increasing tool reliability and simplifying maintenance. The ergonomic handle and clear torque scale support accurate setting and comfortable operation during repetitive tasks.

Suitable for

• Automotive repairs and wheel fastening where precise torque control is required
• Mechanical assembly and maintenance of machinery and equipment
• Service and garage workshops performing routine inspections and fastener replacement
• DIY projects that require controlled tightening of bolts and threaded connections

Key specifications

• Torque range: 19–110 Nm
• Drive size: 3/8" square drive
• Type: Mechanical, adjustable torque wrench with click indication
• Scale: Visible torque scale for setting target torque values
• Construction: Hand-operated steel body with ergonomic handle
• Accuracy: Typical mechanical torque wrench accuracy suitable for professional use (factory-calibrated where applicable)

How to use

Select the appropriate socket for the fastener and attach it to the 3/8" drive. Rotate the adjustment mechanism to set the required torque value within the 19–110 Nm range, using the visible scale to confirm the setting. Apply steady force to the handle while turning the fastener; listen and feel for the characteristic click indicating the set torque has been reached. Stop applying force immediately after the click to avoid exceeding the preset torque. After use, return the adjustment to the lowest setting for storage to reduce spring fatigue and protect calibration.

Usage recommendations

For consistent results, have the torque wrench calibrated periodically according to usage frequency and follow manufacturer guidelines for storage and care. Use impact sockets only with appropriate tools; avoid shock loads and do not use the wrench as a breaker bar. When working on safety-critical assemblies, verify torque values with calibrated instruments after any service involving critical fasteners.
