Torque Wrench 3/8" JCB Model JCB-6473390, 20–120 Nm

3/8" torque wrench by JCB, model JCB-6473390, offers a torque setting range of 20–120 Nm for controlled tightening of bolts and nuts. This compact, medium-duty tool is intended for tasks requiring consistent torque application in automotive repair, machinery maintenance and workshop assembly. The 3/8" drive size balances accessibility in confined spaces with the capacity to handle common fasteners where repeatable torque is needed.

Advantages

The torque wrench provides a clear, adjustable torque range from 20 to 120 Nm that supports accurate tightening and reduces the risk of over- or under-tightening. Its 3/8" drive and compact form factor improve access to moderately tight spaces and make it suitable for a variety of medium-duty fasteners. The tool is designed for repeatable settings, enabling consistent results across multiple fastening operations. Ergonomic handling and a durable construction contribute to reliable use in workshop and maintenance environments.

Suitable for

• Automotive repair and component assembly
• General machinery maintenance and equipment servicing
• Workshop assembly and medium-duty fastening tasks
• Applications requiring repeatable torque settings on bolts and nuts

Key specifications

• Drive size: 3/8" (square drive)
• Torque range: 20–120 Nm
• Application: medium-duty tightening of bolts and nuts
• Form factor: compact wrench suitable for confined spaces
• Adjustment: manual torque setting with repeatable output

How to use

Select the required torque value within the 20–120 Nm range, secure the desired bit or socket onto the 3/8" drive, and apply steady force until the wrench indicates the set torque. Use smooth, controlled movement and avoid sudden jerks. After use, return the torque adjustment to the lowest setting for storage to reduce stress on the mechanism. Follow any manufacturer maintenance guidance for calibration intervals if precise accuracy is required for critical applications.

Usage recommendations

For reliable results, verify calibration periodically and use appropriately sized sockets for the fasteners. Avoid using the wrench as a breaker bar or applying torque beyond the specified range. Store in a dry environment and protect from impacts to maintain accuracy and service life.
