Products Process
Material Selection:
The screws and bolts are made from premium-quality carbon steel or alloy steel that is then galvanized for superior corrosion resistance. This material selection ensures high tensile strength, making these fasteners suitable for demanding automotive applications.
Cold Heading/Forging:
The initial shaping of the screws and bolts is done through cold heading, where the metal is formed under high pressure to create the desired shape without the need for heat. This process improves the mechanical properties of the fasteners and ensures precise dimensions.
Threading:
The threading for the machine screws and bolts is created through CNC machining or tapping processes, ensuring high-precision threads that will securely hold automotive components together, even under vibration or stress.
Galvanization:
The fasteners undergo hot-dip galvanization, where the steel is submerged in molten zinc to form a protective coating. This process ensures a long-lasting, rust-resistant finish that is ideal for automotive environments exposed to moisture, road salts, and other harsh conditions.
Cap Bolt Forming:
The cap bolts are manufactured by precision machining and forging processes to ensure that the head is smooth and provides an optimal fit for wrenches or sockets during installation. The bolts are then galvanized to maintain durability and resistance to environmental wear.
Quality Control & Inspection:
Each batch of screws and bolts undergoes stringent quality control tests, including dimensional checks, tensile strength tests, and corrosion resistance evaluations. The fasteners are also inspected for defects, ensuring they meet industry standards and perform reliably.
Packaging:
Once the fasteners pass quality control checks, they are carefully packaged in bulk or custom packaging. Protective coatings may be applied to avoid scratches or damage during transportation and storage.
Products Application
Automotive Assembly: Used for fastening various parts of the vehicle body, engine components, and chassis. The high strength and corrosion resistance make them ideal for critical automotive applications.
