Because of its small torque value, the most common use scenario is bicycle maintenance, as well as some small motorcycle or even small firearms repair. At present, road cycling is popular among young people and even worldwide, preparing a 1/4 “torque wrench is a good choice.


3/8” Torque Wrench

The 3/8” wrench is the second smallest, and it is also the second most common while being one of the most versatile torque wrenches. It provides a torque range of about 20-100N.m, making it suitable for multiple applications. It is the drive used most for socket sets and engine works, such as in plug tightening,as well as for tightening oversized fasteners and in most small automobiles, from cars to light trucks.


1/2” Torque Wrench

This torque range is usually more than 100 N.m or even several hundred N.m,which making it ideal for tasks involving lug nuts or anywhere on the vehicle suspension. It is suitable for large bolts and nuts like those in engine mounts. Basically, any tightening task for both transmission and suspension, including motorcycles, would require a 1/2 -inch torque wrench.
