What Is a Torque Wrench Used For?

A torque wrench is used to tighten bolts and nuts to a specified torque value instead of relying only on hand feel. This helps reduce the risk of over-tightening or under-tightening during maintenance work.

When Do You Need a 3/4" Torque Wrench?

You need a 3/4" torque wrench when working with larger fasteners or higher torque requirements such as 100–500Nm. This drive size is suitable for workshops handling larger vehicles, equipment, and selected heavy maintenance applications.

Difference Between a Torque Wrench and a Standard Ratchet

A standard ratchet is used for loosening and tightening, but it does not control the torque value. A torque wrench allows the user to set a specific value such as 100–500Nm, making it better for controlled tightening according to service requirements.

Difference Between ANAF2450 and ANAF2470

The ANAF2450 offers a torque range of 100–500Nm and a length of 865 mm, while the ANAF2470 offers a higher range of 140–700Nm and a length of 1092 mm. ANAF2450 is suitable for users who need up to 500Nm, while ANAF2470 is better for higher-torque applications.
