Torque wrench Jonnesway T27030N 1/4" drive, 340 mm, 4.5–30 Nm

Jonnesway T27030N is a 1/4" drive torque wrench with a 340 mm length and a calibrated torque range of 4.5–30 Nm. It is engineered to deliver controlled and repeatable torque for tightening small fasteners where accuracy matters, such as in automotive engine components, bicycle assemblies, and light mechanical equipment. The compact size and clear scale make it suitable for confined workspaces and routine maintenance tasks.

Advantages

The torque wrench features an adjustable scale for precise setting within the 4.5–30 Nm range and a 1/4" drive compatible with common sockets. Its 340 mm length offers a balance between leverage and access in tight areas, while a calibrated mechanism ensures repeatable torque application. The tool is designed for steady handling and reliable performance during assembly and repair operations.

Suitable for

• Automotive light fasteners and engine components
• Bicycle assembly and maintenance
• Small machinery and equipment repairs
• Precision assembly in workshops and service garages

Key specifications

• Drive size: 1/4"
• Overall length: 340 mm
• Torque range: 4.5–30 Nm
• Adjustable torque setting with calibrated scale
• Designed for low to medium torque applications

How to use

Select the required torque value on the adjustable scale, confirm the setting is locked or indicated according to the wrench mechanism, attach the appropriate 1/4" socket, position the socket on the fastener, and apply steady force until the wrench indicates the set torque. Use controlled motion to avoid overshoot and recheck critical fastenings after initial tightening.

Usage recommendations

Use the torque wrench only within its specified 4.5–30 Nm range and with compatible 1/4" sockets. Store the wrench with the torque set to the lowest value to preserve calibration, avoid using it as a breaker bar, and have calibration checked periodically if used frequently in professional settings.
