Auto repair crowd how to choose torque wrench

Torque wrench is a tool commonly used in auto repair operations, can be matched with different specifications of the sleeve for matching use, now the market is common mechanical torque wrench, mainly through the auxiliary sleeve can be moved to control the spring tightness, so as to adjust the size of the torque.

1, check the instructions, select the appropriate torque

Before we choose a torque wrench, it is recommended to consider the use scenario. Bicycle torque range should be 0-25 Nm; The torque of a car engine is generally 30 Nm; The torque required by the motorcycle is usually 5-25Nm, and the torque of individual screws can reach 70Nm. All corresponding torque values are generally marked in the instructions of various products.

2, choose the right drive head

Many DIY owners in the early maintenance only focused on the size of the torque and ignored the matching problem of the sleeve and the drive head, and replaced the sleeve back and forth to delay the maintenance of the car.

1/4 (small fly) drive head is mainly suitable for precision requirements;

3/8 (medium flight) is usually used in cars, motorcycles and bicycles for standard operations, and a wider range of applications;

The 1/2 (Big fly) drive head is mainly an industrial grade operation requirement

3, 72 teeth wider range of application

The higher the number of teeth of the ratchet structure, the smaller the operation Angle required for the same torque demand, and all kinds of small Spaces can be easily dealt with.

4, product quality is the most critical

The key to torsion adjustment is the tightness of the spring, the loose torque is smaller, the tight torque is larger, and the important factor determining the service life of the torque wrench is the quality of the spring. Auto repair crowd torque wrench used more frequently, more attention should be paid to product quality.

5, high precision is more reliable, certificate is indispensable

Torque grades usually have 1-5 grades, and the corresponding 3 grades have repeatability and error within plus-minus 3%; The smaller the error, the more reliable the torque.

The structure and style of the torque wrench are also varied, and the common ones are the pointer torque wrench with preferential price and simple mechanism; Easier to read but slightly more expensive dual window torque wrench.
