In factories filled with the roar of machinery and on precision assembly lines, there exists a seemingly insignificant yet critically important presence—the industrial standard rivet. These metal fasteners, measuring less than a millimeter in diameter, function like the capillaries of industrial civilization, holding together every crucial connection point from automobile chassis to spacecraft structures. As the most fundamental industrial consumable, the standard rivet, with its standardized and high-strength characteristics, has become an indispensable “industrial language” in modern manufacturing.
Diverse Applications of Industrial General-Purpose Nails
- Automotive Manufacturing Sector
In highly automated automotive manufacturing processes, rivets are the core fasteners that ensure the structural integrity and safety of vehicles. During production, each vehicle requires approximately 2,000 standard rivets of different specifications and performance levels for hundreds of critical assembly points, including body panel attachment, welding, chassis structural connections and interior component fixation. These fasteners undergo specialised heat treatment to achieve superior tensile strength and fatigue endurance. They must be able to withstand prolonged exposure to the high-frequency vibrations caused by engine operation, the dynamic impact loads experienced during vehicle movement and the extreme temperature variations ranging from sub-zero temperatures to the high temperatures found within the engine compartment. The premature fatigue failure of any single fastener can lead to joint loosening and abnormal noises, and, in extreme cases, structural safety hazards. Consequently, the performance of these fasteners directly determines the long-term reliability and safety of the vehicle.
- Electronic Device Assembly
Highly integrated electronic devices (such as smartphones, laptops, and communication base stations) rely on miniature stainless steel studs (commonly sized M1.2 to M2.5) for critical internal functions. Their primary role is to securely anchor precision printed circuit boards to device housings or internal brackets within extremely limited space, preventing damage from shifting or vibration during transportation or use. Manufactured from austenitic stainless steel (such as the 304 or 316 series), these studs rely on their exceptional rust and corrosion resistance to effectively withstand erosion from airborne moisture and perspiration. This prevents the migration of conductive ions that could cause short circuits between micro-spaced circuits.
- Building Steel Structures
Hot-dip galvanised standard nails are extensively used for connecting and securing support systems and metal roof/wall panels in large-scale construction and infrastructure projects such as industrial plants, sports stadiums, and skyscrapers. Such structures are exposed to the elements long term and must withstand forces including wind and snow loads, as well as seismic forces. Consequently, the standard nails used must have exceptionally high shear and tensile strengths. Even more critical is their corrosion resistance: the hot-dip galvanising process forms a zinc-iron alloy coating on the nail surface that is typically at least 80 microns thick. This coating acts as a physical barrier, isolating the steel substrate from contact with corrosive agents in humid air and industrial atmospheres. It also provides continuous cathodic protection through electrochemical action at any points where the coating is damaged. This ensures that structural connections will not fail due to corrosion weakening throughout the decades-long design life of the steel structure, thereby safeguarding its overall integrity.
The Technological Evolution and Innovative Breakthroughs at Jett Factory
Material Innovation: Upgrading from traditional carbon steel to titanium alloys and shape memory alloys ensures stable performance of standard screws across temperatures ranging from -196°C to 800°C.
Surface Treatment Technology: Dacromet coating extends salt spray resistance to 1000 hours, meeting marine engineering requirements.
Intelligent Manufacturing: Laser inspection and sorting systems achieve a defect rate of <0.01% per 100,000 standard pins, boosting efficiency by 20 times compared to traditional manual quality control.
Installation Notes
The pilot hole diameter should be 80%-90% of the screw diameter to prevent material cracking. Soft materials like aluminum alloy require a step drilling process.
Power tool torque must be controlled within 0.5-1.5 N·m to prevent stripping. Torque wrenches are recommended for critical connection points, with markings applied.
When combining different materials, consider electrochemical corrosion risks. For example, avoid using standard carbon steel nails directly on aluminum components.
For high-altitude work, use magnetic sockets to prevent standard nails from falling and creating safety hazards.
