Dual Threaded Screw
Products Description
We use top-grade materials for Dual Threaded Screw, including carbon steel, stainless steel, alloy steel, etc. These materials are carefully chosen according to international standards. Carbon steel is suitable for general mechanical applications, offering good strength and affordability. Stainless steel provides excellent corrosion resistance, making it ideal for use in harsh environments or where aesthetic appearance is important. Alloy steel, with its enhanced mechanical properties, is used for high-stress applications.
Products Details
1. Thread Details: The threads of Stainless Screws are full, regular, and with a uniform pitch. Processed using high-precision equipment, they ensure a smooth and tight fit when screwed into the fitting, providing stable tightening force.
2. Head Details: The head shape is precise. Whether it is a cross recess, slotted, or other head type, the grooves are clear and regular, facilitating the precise insertion of installation tools and enhancing installation convenience and efficiency.
3. Surface Details: The surface finish is uniform and fine. For example, the stainless steel surface of Metal Screws has a high gloss and is free of noticeable blemishes or scratches. This not only looks beautiful but also provides excellent corrosion resistance.
4. Shaft Details: The shaft is highly straight, with a smooth transition between the head and threaded portion, free of burrs, bumps, and other defects, ensuring the Steel Screw's overall mechanical properties and smooth operation.
Metal Forming Process
| Raw Material Selection | We rigorously select high-quality metal materials. For example, when producing the Stainless Tek Screws series of stud screws, we use high-quality steel that meets industry standards to ensure that the raw material's mechanical and chemical properties meet subsequent processing requirements. |
| Forging | Through the forging process, the raw metal is shaped, resulting in a denser internal structure, improved strength and toughness, and a good foundation for subsequent thread processing and other processes. |
| Heat Treatment | Heat treatments such as quenching and tempering are performed on the forged metal. Precisely controlling the temperature and time adjusts the metal's microstructure, further optimizing its hardness, wear resistance, and other properties, ensuring the Metal Screws' durability. |
| Surface Treatment | Surface treatments such as electroplating and passivation are used according to specific requirements. For example, some metal screws are galvanized, which not only enhances corrosion resistance but also improves the Steel Screw's appearance and quality. |
Manufacturing Process
Threading: High-precision threading equipment, such as thread rolling machines, is used to thread the metal blank, ensuring accurate thread profile, pitch, and other parameters, ensuring the connection accuracy of the Stainless Tek Screws.
Head Forming: Through cold or hot forging, the head of the Stainless Screws is formed into a shape that meets design requirements, such as a common Phillips head or slotted head, while also ensuring the strength of the connection between the head and the shank.
Precision Testing: During the production process, multiple precision testing steps are implemented, using specialized testing equipment to thoroughly inspect the Metal Screw's dimensions, thread accuracy, and mechanical properties, ensuring that every product meets quality standards.
Surface Treatment Refinement: For Dual Threaded Screws requiring special surface treatment, more sophisticated surface treatment processes are used. This not only ensures functional requirements such as corrosion resistance, but also ensures aesthetics and consistency.
