In a machine as large and sophisticated as an aircraft, every screw carries a significant responsibility. They connect critical structures such as the wings, fuselage, and engines, directly impacting flight safety and stability.
Aircraft screws must maintain their strength and stability even in extreme environments. Whether facing low temperatures and humidity fluctuations at high altitudes or enduring intense vibrations during takeoff and landing, these screws must remain rock-solid.
As a result, aviation screws typically possess three distinct characteristics: high strength, light weight, and excellent corrosion resistance. Jinxin Company has long specialized in the production of high-performance fasteners, using premium tungsten steel, titanium alloy, and stainless steel to ensure reliable performance in high-vibration and high-stress conditions.
Not all parts of an aircraft use the same type of screw—different structures require different fasteners:
AN bolts (Army-Navy bolts): Highly precise and versatile, used in structural areas such as the fuselage and wings.
MS bolts (Military Standard bolts): Installed in critical load-bearing areas and manufactured to meet stringent military standards.
NAS bolts (National Aerospace Standard bolts): Designed for higher strength, commonly used in engines and landing gear systems.
Titanium alloy screws: Lightweight yet extremely strong, a popular choice in modern passenger aircraft.
Stainless steel and nickel-based alloy screws: Ideal for high-temperature areas such as engine covers and exhaust systems.
To ensure long-term performance in diverse environments, aircraft screws often undergo specialized surface treatments such as anodizing, cadmium plating, or phosphating. These processes significantly enhance corrosion and wear resistance.
Screwsused in aircraft are the result of precision engineering and high-standard manufacturing. They represent the highest level of technology in the fastener industry. At Jinxin, we utilize advanced heat treatment and coating technologies to further enhance surface strength and extend service life. Before shipment, every screw undergoes rigorous testing to ensure compliance with international standards such as NAS, MS, and AN.
