Preset Non Adjustable Torque Wrench

The SDX-330HP fixed value torque wrench does not have a ruler, scale line and dividing wheel, and the torque indication cannot be set intuitively from the torque wrench. When the product leaves the factory, it is adjusted to the required torque indication according to customer needs. This product is generally suitable for use in assembly lines with fixed torque indications.

Preset non adjustable torque wrench is a special tool for accurately controlling the tightening torque of bolts and nuts, and is mainly used in the following scenarios.

1. Automobile repair and manufacturing: In the process of automobile repair and manufacturing, the tightening torque of bolts and nuts needs to be strictly controlled to ensure the safety and reliability of the vehicle. Preset non adjustable torque wrench can provide accurate torque output to avoid failures caused by overtightening or over-loosening. For example, in the assembly of key components such as engines, suspension systems and brake systems, preset non adjustable torque wrenches are widely used.

2. Aerospace: The aerospace field has extremely high requirements for the accuracy and reliability of parts. Preset non adjustable torque wrenches can ensure that key bolts and nuts reach the predetermined tightening torque, thereby ensuring the structural integrity and safety of aircraft and spacecraft. In the assembly and maintenance of aircraft engines, wings and landing gear, preset non adjustable torque wrenches are indispensable tools.

3. Precision machinery and instruments: In the manufacturing and maintenance of precision machinery and instruments, there are strict requirements for the tightening torque of bolts and nuts. Preset non-adjustable torque wrenches can provide precise torque control to meet these requirements. For example, preset non-adjustable torque wrenches are widely used in the assembly of optical instruments, medical devices and precision machine tools.

4. Other industrial fields: In addition to the above fields, preset non-adjustable torque wrenches are also widely used in other industrial fields that require precise control of bolt and nut tightening torque, such as heavy machinery manufacturing, power equipment and chemical equipment, etc., where fixed torque assembly lines are required.

When using preset non-adjustable torque wrenches, pay attention to the following matters:

• Do not use preset torque wrenches to remove bolts or nuts to avoid damage to the tool or affect the accuracy.

• It is strictly forbidden to add a sleeve extension arm to the end of the torque wrench to prevent damage to the torque wrench.

• Adjust the required torque as needed, and ensure that the adjustment mechanism is in a locked state before use.

• When using a torque wrench, load it slowly and evenly, and do not pull or press it hard to avoid overload and misalignment of the output torque. After reaching the preset torque, the loading force should be stopped.
