Some of the special-shaped parts processing is not up to standard, in use will cause the screws and nuts with regret can not be opened. This situation is called locked. In this case, the special-shaped parts manufacturers think that the mitigation methods are as follows:

Reduce friction coefficient. For example: threads must be kept clean. Add lubricant before use.

Use the correct method of operation. For example: the nut must be perpendicular to the axis of the screws are screwed, have prohibited any tilt; when screwing the applied force must be uniform, force shall not exceed the safe torque; as much as possible using the torque wrench or socket wrench, prohibited the use of adjustable wrench or electric wrench; if when used in high temperature it must first cooling, and strictly prohibited the rapid rotation of the situation at the time of installation, which can avoid too fast because of the temperature near the lock because of the emergence of the.

Choose the right product. When in use, we must first understand the mechanical properties of the products can meet the requirements of use; the length of the bolt must choose the right, are usually exposed to a screw after two teeth from a.. The above is our professional manufacturers to introduce you.
