Specification of SS304 Threaded Rod:

The specification of ss304 threaded rod refers to its specific dimensions, thread pitch, and other mechanical properties.

Product namess304 threaded rod
Thread Diameter:The thread diameter is the measurement of the major diameter of the threaded portion of the rod. It represents the outer diameter of the threaded section and determines the size of the fastener or the hole it fits into. For instance, in the case of an M8 threaded rod, the thread diameter would be 8 millimeters for metric threads, while for imperial threads, it could be expressed as 1/4", 3/8", etc.
Thread Length:The thread length is the measurement of the portion of the rod that is threaded, extending from one end to the other. It indicates the distance over which the threads are present and can be engaged with nuts, bolts, or other threaded components. Thread length is typically specified in millimeters or inches, depending on the system of measurement being used.
Material:ASTM 304 stainless steel in the United States or 1.4301 in the European standard. This steel is composed of iron, 18% chromium, and 8% nickel, providing good corrosion resistance
Strength Grade: 700 MPa (min)
Industry Standards:DIN975 / ASME B 18.31.3
Packaging:cartons into wooden pallets
Application:Construction/Automotive/Marine/Aerospace/Food and Beverage Industry/Medical Equipment/Chemical Processing/Water Treatment

Production process threaded rod:

Production Procession of Hex Bolts
1. Wire Drawing:
The production process begins with drawing stainless steel wire through a series of dies to reduce its diameter and achieve the desired size for the threaded rod. This process involves pulling the wire through progressively smaller dies until the desired diameter is reached.
2. Cutting:
- Once the wire is drawn to the required diameter, it is cut into specific lengths using cutting machines. These lengths will become individual threaded rods.
3. Chamfering:
- After cutting, the ends of the threaded rods are chamfered to remove sharp edges and facilitate easy threading during assembly. Chamfering is typically done using specialized chamfering machines or tools.
4. Threading Rolling:
- The chamfered rods are then fed into threading rolling machines, where threads are formed through a cold-working process. Thread rolling involves applying pressure to the rod between two dies, causing the material to deform and form the threads. This method produces threads with excellent strength and precision.
6. Surface Treatment:
- After heat treatment, the threaded rods may undergo surface treatment processes to improve their appearance and corrosion resistance. Common surface treatments include polishing, passivation (chemical treatment to remove surface contaminants), or coating with zinc, chrome, or other corrosion-resistant materials.
7. Quality Control and Packaging:
- Throughout the production process, quality control measures are implemented to ensure that the threaded rods meet specified standards and tolerances. Once the rods pass inspection, they are packaged according to customer requirements, which may include bundling, labeling, and protection against damage during shipping and handling.

Application of ss304 threaded rod:

SS304 threaded rods, made of stainless steel, are widely used for their corrosion resistance and durability. They serve diverse applications across industries such as construction, mechanical engineering, marine, and food processing. These rods provide stability, structural support, and corrosion resistance in harsh environments. In essence, SS304 threaded rods are indispensable components known for their reliability and versatility across various sectors.

Construction and Infrastructure:SS304 threaded rods are used in construction for structural support, anchoring, and fastening purposes. They are often used in conjunction with nuts, washers, and other fasteners to provide stability and strength in building structures, bridges, and infrastructure projects.
Mechanical and Industrial Engineering:In mechanical and industrial engineering applications, SS304 threaded rods are utilized for assembling machinery, equipment, and components. They provide a reliable means of securing parts together in applications such as automotive manufacturing, machinery assembly, and industrial maintenance.
Electrical and Electronics:SS304 threaded rods are used in electrical and electronic applications for mounting and securing components, fixtures, and enclosures. They provide a corrosion-resistant and stable mounting solution in environments where exposure to moisture, chemicals, and other corrosive substances is a concern.
Marine and Coastal Applications:Due to their corrosion resistance, SS304 threaded rods are commonly used in marine and coastal environments where exposure to saltwater and harsh weather conditions can cause corrosion and degradation of traditional fasteners. They are employed in marine construction, boat building, dock installations, and offshore structures.
Food and Beverage Industry:In the food and beverage industry, where hygiene and cleanliness are paramount, SS304 threaded rods are used in equipment and machinery assembly. Their resistance to corrosion and ability to withstand frequent cleaning and sanitation make them suitable for use in food processing plants, breweries, and commercial kitchens.
Chemical and Pharmaceutical Industry:SS304 threaded rods are employed in chemical and pharmaceutical processing facilities for assembling equipment, piping systems, and structural components. Their resistance to corrosion from chemicals and sanitizing agents makes them ideal for use in corrosive environments.
Agricultural and Horticultural Applications:In agricultural and horticultural settings, SS304 threaded rods are used for constructing greenhouses, trellises, and support structures for plants and crops. Their durability and resistance to environmental factors make them suitable for outdoor applications where exposure to moisture and temperature variations is common.

Quality control of SS304 Threaded Rod:

Control MethodDetail
Material Inspection:Verify the material's composition, heat treatment, and quality upon receipt. Conduct metallurgical analysis to ensure the material properties meet the standards.
Process Control:Implement strict process control measures for heat treatment, machining, threading, and any other manufacturing steps. Maintain consistent process parameters to ensure uniform quality.
Inspection Points:Introduce inspection points at various stages of manufacturing to check for defects, dimensions, and quality. Inspect threading, dimensions, surface finish, and other critical parameters.
Sampling and Testing:Regularly sample products for testing, such as tensile testing, hardness testing, and metallurgical analysis, to ensure they meet the required specifications.
Thread Inspection:Thoroughly inspect threading using proper thread gauges to ensure accurate dimensions and fit with mating components.
Traceability:Implement a traceability system to track each fasteners journey from raw material to final product. This aids in accountability and recalls if necessary.
