It covers multiple areas of a vehicle, including the body structure, chassis system, interior, exterior, power train, and more. These parts are essential components that ensure the functionality, safety, and durability of the automobile.

Gaskets: metal flat washers, spring lock washers, used to prevent bolt loosening and provide sealing.

Pins: Dowel Pins (e.g., for locating engine components) and Split Pins (to prevent nuts from coming loose).

Springs: seat return springs, door check spring, valve springs, etc., which provide elastic force.

Clamps: metal hose clamps for securing pipelines such as fuel lines and water hoses.

The normal operation of charging stations relies on various hardware components, which play critical roles in structural fastening, electrical connections, and safety protection.

Expansion Bolts: Used to secure charging pile bases, brackets, etc., to the ground or walls. They are commonly made of carbon steel and have high load-bearing capacity.

Angle Steel / Channel Steel: Commonly used to fabricate support frames or cable trays for charging piles, providing structural stability. The material is typically Q235 steel.

U-bolts: Used to secure cables, pipes, or equipment brackets, preventing loosening, and suitable for fixing cylindrical objects of various specifications.

The normal operation of railway systems relies on a large number of hardware components, which play critical roles in various aspects such as track structures, vehicle connections, signaling equipment, and infrastructure, ensuring the safety, stability, and durability of the railway.

Fishplate (Rail Joint Bar): Connects the ends of two steel rails, typically made of high manganese steel or high-quality carbon steel, secured with bolts to ensure the smoothness and strength of the rail joint.

Track Bolts and Nuts: Used in conjunction with fishplates, typically high-strength bolts (e.g., Grade 8.8, Grade 10.9), with phosphated or galvanized surfaces for corrosion resistance and capable of withstanding train impact loads.

The proper operation and structural stability of household appliances rely on various hardware components, which play critical roles in connection, fastening, transmission, and protection.

Screws / Bolts: Regular carbon steel screws (for internal, non-exposed components) and stainless steel screws (for appliances in humid environments, such as washing machines and refrigerators).

Nuts and Washers: Nuts: Used with bolts, commonly hex nuts, some with non-slip ribs (e.g., for fixing appliance bases); nylon lock nuts (for vibrating components, such as washing machine motors).

Medical equipment places extremely high demands on the precision, stability, corrosion resistance, and safety of hardware components, with requirements varying across different types of equipment due to functional differences.

Aluminum Alloy Profiles (e.g., medical bed frames, equipment housing brackets): Lightweight and corrosion-resistant, facilitating easy processing and assembly.

Special Screws (e.g., lock screws, screws for sterile environments): Prevent loosening during equipment operation and can withstand high-temperature sterilization.

Precision Gears (e.g., valve drive mechanisms in ventilators): Control the opening and closing accuracy of airflow valves to ensure stable respiratory parameters.

The operation of communication equipment (such as smartphones, base stations, switches, routers, and fiber optic equipment) relies on precise structural support, signal transmission, and protection. Hardware components play critical roles in fastening, connecting, shielding, and heat dissipation within these systems.

Micro Screws (e.g., smartphone motherboard fixing screws, base station module screws): Typically made of stainless steel or high-strength aluminum alloy, with cross, hex, or Torx heads, some featuring anti-loosening coatings (such as nylon patch) to prevent loosening caused by device vibration.

Stainless Steel Brackets (e.g., internal base station motherboard mounting brackets): Primarily made of 304 stainless steel, offering strong corrosion resistance, suitable for harsh environments like outdoor base stations (humid, dusty), and capable of supporting heavy motherboards or power modules.

The operation of communication equipment (e.g., smartphones, base stations, switches, routers, fiber optic devices) relies on precise structural support, signal transmission, and protection. Hardware components play critical roles in fastening, connecting, shielding, and heat dissipation within these systems.

Copper Alloy Pins/Sockets (e.g., Ethernet port interfaces, SIM card slot internal terminals): Made of brass (H62) or phosphor bronze, with nickel or gold plating (to enhance conductivity and plugging durability), ensuring signal transmission without attenuation (e.g., high-speed connectors for 5G equipment need to support transmission rates above 10 Gbps).
