What is a Special Screws?

1. Definition and classification of special screws

Special screws are threaded connectors that are improved or designed on the basis of ordinary screws. Their shapes and sizes are different from standard threads and are suitable for some special connection requirements. According to their uses and characteristics, special screws can be divided into the following categories:

1. Stainless steel special screws: high temperature and corrosion resistance, widely used in chemical, petrochemical, marine and other fields.

2. Fastening ring special screws: because their fixing torque can be automatically adjusted, they are widely used in high-tech fields such as aviation and aerospace.

3. High-strength special screws: high strength and long service life, suitable for transportation, machinery and other fields.

4. Other special screws: such as special screws with washers, special screws with wedge-shaped safety holes, etc.

2. Characteristics and application fields of special screws

Compared with ordinary screws, special screws have the following characteristics:

1. They can adapt to different connection requirements and can be used in various complex working conditions.

2. Superior performance, with high strength, corrosion resistance, high temperature resistance, wear resistance and other characteristics.

3. High precision, can achieve higher working accuracy and quality standards.

4. Good safety performance, can provide reliable protection and guarantee.

The application fields of special screws are very wide, mainly including:

1. Aviation and aerospace fields: The high temperature resistance, high strength and safety performance of special screws are necessary to meet the high standards of connectors in the aerospace field.

2. Mechanical field: Special screws are widely used in the connection of mechanical structures such as sliding bearings, gear transmissions, and sealed transmissions, which can improve the performance and life of products.

3. Chemical, petrochemical, and marine fields: Special screws are used in places where they are resistant to high temperatures, corrosion, and prevent erosion from the marine environment, and can provide more reliable protection for these fields.

4. Other fields: Special screws are also widely used in electronics, communications, automobiles, medical and other fields.

3. Uses and advantages of special screws

1. Uses of stainless steel special screws: Stainless steel special screws are mainly used in places with corrosion and high temperature environments, such as marine, petrochemical, chemical and other fields. Compared with other materials, they have higher corrosion resistance and better high temperature resistance, avoiding accidents caused by corrosion and aging of connectors.

2. Uses of fastening ring special screws: Fastening ring special screws are suitable for occasions that require automatic adjustment of torque and locking torque, such as aviation, aerospace and other fields.

3. Uses of high-strength special screws: High-strength special screws are mainly used in occasions that require important engineering structures, such as bridges, dams, highways, etc.

4. Uses of special screws with washers: Special screws with washers are mainly used in occasions that need to increase pressure and shorten thread length, such as Pipeline.

5. Uses of special screws with wedge-shaped safety holes: Special screws with wedge-shaped safety holes are mainly used in occasions that need to protect machines and equipment from being damaged, such as ATM machines, security doors, etc.

In short, special screws are widely used in various fields due to their unique advantages, and they can provide reliable protection for the needs of all walks of life.
