Reversible torque wrench 1/2" TOP-08-837, 60–330 Nm torque range

The reversible torque wrench 1/2" TOP-08-837 offers controlled tightening and loosening of fasteners across a 60–330 Nm torque range. Built around a 1/2" drive and a reversible ratchet head, this tool delivers repeatable torque application for jobs where consistent fastness is required. It is designed for use in automotive, industrial and workshop environments to help prevent under- or over-tightening of bolts and nuts.

Advantages

This 1/2" reversible torque wrench provides a wide working range from 60 to 330 Nm, enabling use on medium to heavy-duty fasteners. The reversible ratchet head permits quick switching between tightening and loosening without removing the tool from the fastener. The calibrated torque mechanism ensures repeatable results and improves joint reliability. Its robust construction suits frequent workshop use while maintaining measurement stability throughout the specified range.

Suitable for

• Automotive maintenance and repair tasks (engine, suspension, drivetrain)
• Industrial assembly and machinery maintenance
• General workshop and service centre fastening work
• Applications requiring mid-to-high torque settings for bolts and nuts

Key specifications

• Drive size: 1/2 inch
• Torque range: 60–330 Nm
• Reversible ratchet head for forward and reverse operation
• Calibration-adjustable torque mechanism for repeatable settings
• Suitable for medium- to heavy-duty fasteners

How to use

Select the required torque within the 60–330 Nm range according to the fastener specification and vehicle or equipment manual. Fit the appropriate socket onto the 1/2" drive, place the wrench squarely on the fastener and apply steady, even force until the torque mechanism indicates the set value. To change direction, use the reversible ratchet head to switch between tightening and loosening without removing the tool. After use, return the torque setting to its lowest value if recommended by the manufacturer and store the wrench in a dry, safe place.

Usage recommendations

For accurate results, have the torque wrench periodically checked and recalibrated according to the frequency of use. Use sockets and accessories that match the drive size and avoid applying impact force or using the tool with extension bars that alter the effective torque unless compensated for. Follow equipment or vehicle manufacturer torque specifications to ensure correct joint tension.
