The aerospace sector places considerable demands on fasteners to ensure the stability of the structure under extreme working conditions. Adaptable to extreme moisture, marine environments or other corrosive conditions. Suitable for high altitude, vacuum or very low temperatures. And its own light weight, can resist due to vibration or shock caused by loosening or damage.
1. Bolts
Bolts are used to connect various components of aerospace vehicles, commonly used in the fuselage, engine, landing gear, wings and other structural components of the aircraft fixed. Usually use high-strength alloy steel, titanium alloy, aluminum alloy, Inconel alloy and so on.
2. Screws
Screws are widely used to connect small components of aerospace vehicles, such as electronic equipment, instruments, sensors and so on. Stainless steel, titanium alloy, aluminum alloy, etc. are often used.
3.Nuts
Nuts are used in conjunction with bolts to fix the structure of aerospace vehicles. Usually use steel alloy, aluminum alloy, titanium alloy and other high-strength materials. Self-locking nuts are sometimes used to prevent loosening in vibration or shock environments.
4.Washers
Washers are used between bolts or screws and fixed parts to spread the load, reduce wear and tear, prevent leakage or prevent loosening. Usually aluminum alloy, copper alloy, stainless steel and so on.
Flat washers: spread the load
Spring washers: used to prevent loosening
Sealing washers: used to prevent leakage, commonly used in hydraulic or fuel system sealing.
5. Rivets
Used for permanent connections, commonly used for fuselage shell connections, panels, hatches, window frames, etc. Common materials include aluminum alloys, titanium alloys, steel alloys, etc.
6. Pin
Pins are used to connect moving parts in aerospace vehicles, such as landing gear, rudder control and so on. Stainless steel, titanium alloy, aluminum alloy, etc. are usually used. Common pins include cylindrical pins, locating pins, spring pins and so on.
7.Spring
Used to provide variable force, used in a variety of aerospace vehicle control systems, shock absorption systems, etc.. Commonly used materials include stainless steel, titanium alloy, alloy steel and so on. Commonly used are compression springs, extension springs, torsion springs and so on.
8.Self-locking parts
Self-locking fasteners are mainly used to prevent loosening due to vibration or external forces, and are widely used in key components of aerospace vehicles. High-strength alloy steel, titanium alloys and so on.
