Torque wrench JCB 3/8" 5–25 Nm, reversible ratchet torque spanner

Handheld torque wrench JCB 3/8" 5–25 Nm is a reversible ratchet torque spanner designed for accurate torque application on bolts and nuts within a low to medium torque range. The tool features a 3/8" drive and an adjustable scale that lets the user set torque between 5 and 25 Nm. Its reversible ratchet head enables both tightening and loosening without changing sockets, making it suitable for maintenance, automotive and assembly tasks that require repeatable, controlled tightening.

Advantages

The adjustable torque range of 5–25 Nm accommodates a variety of small to medium fasteners, while the 3/8" drive supports a wide selection of sockets. The reversible ratchet head improves workflow by allowing direction changes quickly. A clear torque scale provides visual confirmation of the set value for consistent results. The handheld, compact design supports access in confined spaces and manual control during torque application.

Suitable for

• Automotive service on components requiring low-to-medium torque
• Mechanical and equipment maintenance
• Precision assembly of machinery and appliances
• Bicycle and motorcycle repairs with specified torque values
• Workshop tasks where repeatable torque settings are needed

Key specifications

• Drive size: 3/8"
• Torque range: 5–25 Nm
• Head type: reversible ratchet
• Adjustment: manual scale for setting target torque
• Operation: handheld, manual torque application

How to use

Set the torque wrench to the required torque value using the visible scale. Fit the appropriate 3/8" socket to the drive and place it on the fastener. Apply steady, even force until the wrench indicates the set torque or the ratchet mechanism signals torque attainment. Use the reversible ratchet head to change the direction for loosening without removing the socket. After use, return the adjustment to the lowest setting to relieve spring tension and store in a dry place.

Usage recommendations

Use the torque wrench only within the specified 5–25 Nm range to ensure accuracy. Avoid applying sudden impacts or using the wrench as a breaker bar. Calibrate the tool periodically according to usage frequency and follow standard safety procedures when working on pressurized or live systems.
