Fasteners by Types
SSM’s product range comprises steel pipes, pipe fittings, flanges, fasteners, plates, and bars. We provide a wide range of standard and custom products to fulfill your various requirements.
Hex Bolt
This type of bolt has a hexagonal head and is commonly used with a nut to secure parts together. It is often used in applications that require strong and reliable connections.
Hex Nut
An essential fastener that is used with a hexagonal head bolt to tighten and secure parts together.
Hex Socket Cap Screw
This screw features a hexagonal socket hole and does not need a nut. It is suitable for applications that require a low-profile head and clean appearance.
Stud Bolt
A type of bolt with threads on both ends, often used with a nut on one end, and a nut or connector on the other. It is commonly used in connections that require frequent disassembly.
Threaded Rod
This rod has continuous threads and is used for adjusting spacing or as an extension of a bolt.
Washer
Typically round in shape, it helps distribute the pressure of the fastener and reduces the risk of loosening or damaging the surface.

How Fasteners Are Made
The production of fasteners typically involves several basic steps and processes:
1. Material selection: Depending on the fastener’s purpose and requirements, the appropriate material is chosen, such as carbon steel, stainless steel, alloy steel, or special alloys like Monel, Inconel, etc.
2. Cold Heading: Most fasteners are manufactured through cold heading. In this process, the metal rod is cut into suitable lengths and formed into a head (such as a hexagonal or concave head) by a cold heading machine.
3. Forming and shaping: After cold heading, the threads and body are precisely formed and shaped by dies and mechanical operations to ensure the fastener’s accurate size and quality.
4. Heat treatment: Some fasteners require heat treatment to enhance their strength and durability. Heat treatment involves heating to a specific temperature and then quenching or annealing to change their internal structure.
5. Surface treatment: The fastener’s surface may need to be plated or coated to increase its corrosion resistance or improve its appearance. Common surface treatment methods include zinc plating, nickel plating, chrome plating, or applying organic coatings.
6. Quality Control: Stringent quality control and testing are carried out at every stage of the manufacturing process to ensure that the fasteners meet the specified size, strength, and other technical requirements.
7. Packaging and marking: Upon completion, the fasteners are usually packaged according to customer requirements and marked to show the model, size, and relevant technical specifications for correct use and identification.
These steps and processes help ensure the high quality and reliability of fasteners, which are essential in various industrial applications.
Use and Maintenance
Fasteners are essential in industrial and construction settings. Proper use and maintenance are crucial to ensure their functionality and safety. Here are some guidelines:
Use
1. Proper selection: Choose the right type, material, and specification based on the application environment and requirements.
2. Proper installation: Use correct tools and techniques to ensure the fasteners reach the appropriate preload.
3. Follow the specifications: Adhere to installation guidelines and technical specifications provided by the manufacturer.
4. Prevent loosening: Use anti-loosening devices or coatings, especially in vibration environments.
5. Regular inspection: Check the condition and tightness of fasteners regularly and promptly adjust or replace damaged parts.
Maintenance
1. Prevent corrosion: Regularly inspect and maintain anti-corrosion coatings like plating or coatings.
2. Keep clean: Ensure that fasteners and the surrounding area are kept clean to prevent the accumulation of dirt or corrosive substances.
3. Replace damaged parts: Promptly replace aged or damaged fasteners to avoid safety and functional issues.
4. Use the right tools: Use the appropriate tools and techniques to prevent damage to fasteners and related components.
5. Record maintenance: Maintain a record of installation and maintenance history, including inspection dates and replacement records for traceability and management.
By following these guidelines, fasteners can remain efficient, safe, and reliable for long-term use.
