Types and Uses of Aerospace-Grade Fasteners
Fasteners are an essential component in the aviation industry, ensuring the structural stability and safety of aircraft. The aerospace sector demands high-performance fasteners in aircraft that can withstand extreme conditions such as high-speed air pressure, mechanical stress, corrosion, and vibrations. These fasteners hold together crucial parts of an aircraft, including the fuselage, wings, landing gears, and engines.
At Vision Alloys, we supply aerospace-grade fasteners such as SS 304 fasteners, SS 316 fasteners, Inconel 718 fasteners, Titanium fasteners, and Duplex Steel 2205 fasteners, all designed to meet the stringent quality and safety standards required in aircraft manufacturing and maintenance.
Importance of Fasteners in Aircraft
The aviation industry requires fasteners used in aircraft that offer high strength, durability, and resistance to extreme temperatures and atmospheric conditions. Unlike standard industrial fasteners, aerospace fasteners must meet specific requirements set by regulatory bodies such as ASTM, ASME, MIL-SPEC, and SAE Aerospace Standards.
Aircraft are subjected to continuous vibration and immense structural stress. Using substandard fasteners can lead to catastrophic failures. This is why aircraft fasteners are manufactured with high-quality materials like stainless steel, titanium, nickel alloys, and duplex steel to ensure superior tensile strength, corrosion resistance, and thermal stability.
Types of Fasteners Used in Aircraft
There are several types of fasteners used in aircraft, each serving a specific function. Some of the most widely used fasteners include:
1. Bolts and Screws
Bolts and screws are among the most commonly used fasteners in aircraft, providing structural support in fuselage assembly, wings, and landing gear. These fasteners must have excellent load-bearing capabilities to sustain aerodynamic stress.
Common types include:
- SS 304 Bolts & Screws – Corrosion-resistant and used in non-structural aircraft applications.
- Titanium Screws – Lightweight and highly durable, ideal for engine components and high-stress areas.
- Inconel 625 Bolts – High-temperature resistant, used in jet engine parts.
2. Rivets
Rivets play a crucial role in aircraft manufacturing, particularly in securing the fuselage skin, wings, and panels. Unlike bolts and screws, rivets do not require threading, making them ideal for aircraft body assemblies where aerodynamic smoothness is essential.
Common rivet materials include:
- Aluminum Rivets – Lightweight and widely used in aircraft structural components.
- SS 316 Rivets – Offer superior corrosion resistance in marine and aerospace environments.
3. Pins and Cotter Pins
These fasteners are commonly used to secure moving parts such as hinges, control surfaces, and landing gears. They ensure that rotating or oscillating components remain in position without the risk of loosening.
Examples:
- Duplex Steel 2205 Pins – Provide high strength and corrosion resistance.
- Titanium Cotter Pins – Ideal for aerospace applications due to their lightweight and anti-corrosive properties.
4. Nuts and Washers
Nuts and washers complement bolts and screws, providing extra grip and preventing loosening due to aircraft vibrations. They also help in distributing loads evenly.
Common types include:
- SS 316 Nuts & Washers – Highly resistant to saltwater corrosion, making them ideal for aerospace applications.
- Inconel 718 Washers – Exceptional performance in high-temperature environments, such as jet engines.
5. Clamps and Clips
Aircraft wiring, hydraulic lines, and fuel systems require secure fastening using clamps and clips. These ensure stability and organization in aircraft interiors and technical compartments.
Examples:
- SS 304 Clamps – Used for securing hydraulic pipes and cables.
- Titanium Clips – Lightweight and strong, ideal for securing electrical wiring in aircraft.
