Click torque wrench Hazet 5123-2CLT — mechanical 1/2" drive, torque in Nm, includes ratchet attachment

Hazet 5123-2CLT is a mechanical click torque wrench with a 1/2" (12.5 mm) solid square drive. Calibrated to read torque in newton-metres (Nm), it gives a clear audible and tactile click when the preset torque is reached, supporting accurate tightening in workshop and automotive tasks. The tool is supplied with a ratchet attachment for added versatility.

Advantages

The wrench offers a measured torque range from 60 to 320 Nm with a stated tolerance of 4%, enabling repeatable tightening within that span. Its solid 12.5 mm (1/2") square drive accepts common sockets and the included ratchet attachment increases accessibility in confined spaces. The mechanical click indication requires no batteries and provides reliable feedback when the set torque is achieved.

Suitable for

• Tightening wheel nuts and suspension fasteners on passenger cars and light commercial vehicles
• General workshop assembly and maintenance requiring medium to high torque
• Automotive repair tasks where a 1/2" drive and tactile click feedback are preferred

When it may not be suitable

This wrench's lower limit of 60 Nm makes it unsuitable for precision work requiring very low torque values, such as delicate electronics or small fasteners. Also, for torque requirements above 320 Nm or where a digital readout and data logging are necessary, a different torque tool would be more appropriate.

Key specifications

• Torque range: 60–320 Nm
• Tolerance/accuracy: ±4%
• Drive type: solid square 12.5 mm (1/2")
• Indication: mechanical audible and tactile click at set torque
• Accessories: includes ratchet attachment

How to use

Set the desired torque value on the handle according to the manufacturer's scale, attach an appropriate socket to the 1/2" square drive or use the supplied ratchet attachment, then apply steady force until you hear and feel the click. Release pressure immediately after the click to avoid over-torquing. Store the wrench with the setting returned to the minimum torque to preserve calibration.

What to consider before purchase

• Required torque range for your tasks (60–320 Nm)
• Need for a 1/2" (12.5 mm) drive and compatibility with existing sockets
• Preference for mechanical click feedback versus digital readout or data logging

Usage recommendations

For consistent results, verify calibration periodically, use the correct socket fit, and avoid applying sudden jerks. Return the wrench to its lowest setting after use and keep it clean and dry to maintain accuracy.
