What are the anti-loosening methods of fasteners?

2022/06/23

Mechanical fasteners are used to fix and pin between the threaded piece and the connected piece or between the threaded piece and the threaded piece to prevent loosening. The advantage of this method is that it is reliable to prevent loosening, which generally depends on the static strength or fatigue strength of the mechanical fastener (or the fastener itself, such as a slotted nut).

What is a lock screw? What does it do?

Anti-loosening screws are screws that prevent loosening. The screws must achieve the effect of anti-loosening. They are mainly used to process special engineering plastics on the screw teeth. During the locking process, the screw nut can be compressed due to engineering plastics. Weak friction torque and anti-chemical force occur, full-tooth joint contact occurs, and relative resistance to vibration is supplied, making ordinary screws a powerful anti-loosening screw, completely solve the problem of loose screw nut.

Briefly describe the difference between mechanical nails and self-tapping nails

Self-tapping screws do not need to be equipped with nuts. They are screwed in and drilled out threads on the material at the same time. They are generally used on materials with low hardness. For example, a self-tapping screw is screwed into a board. The board does not need to have a pre-drilled threaded hole. The machine thread screw must have a pre-punted hole and a good thread, and then take the matching screw to screw in.

How to choose screw material?

Screws are mechanical basic parts and are in great demand. Usually bolts, screws, rivets, etc. are used to ensure safety or generally do not need to consider the impact of temperature in harsh environments or other dangerous working conditions. Commonly used materials are carbon steel, low alloy steel and non-ferrous metals. However, in certain occasions, fastener materials need to meet the conditions of severe corrosion or high strength, and many stainless steels and ultra-high strength stainless steels have emerged.
