The Complete Guide to Aerospace Fasteners 2023

The aerospace fastener is an essential part of aerospace equipment which is the core product of modern aviation industry. The main function of air fasteners is to ensure the safety and stability of aircraft during flight, so its quality and reliability are of great importance. With the continuous development of the aviation industry and the continuous upgrading of aircraft, the demand for aircraft fasteners will be more high-end, diversified and personalized. Now, let’s learn more details about aerospace fasteners, including their types, features, materials, etc.



What are Aerospace Fasteners?

Aerospace fasteners are types of hardware used to attach parts and components in the aerospace industry. They play an important role in the manufacture and maintenance of aircraft structures. They are typically made of metal alloys such as steel, aluminum, titanium, and nickel-based alloys, and they come in various shapes and sizes. Aerospace fasteners are designed to withstand extreme temperatures, high pressures, and harsh environments.

There are some common types of aerospace fasteners including bolts, screws, nuts, rivets, pins, and clips. They are widely used in the connection and fixation of aircraft wings, fuselage, landing gear, engines, doors and other parts. Besides, air fasteners are essential components in aerospace engineering, and they must meet strict standards for strength, reliability, and safety. For example, they must be created with high durability and first-class quality.

The Characteristics of Aerospace Fasteners

Aerospace fasteners, as an indispensable part of aviation manufacturing, play an important role in connecting, fixing and protecting various parts of aircraft. Their characteristics and attributes determine the safety and reliability of the whole aircraft. Here we will give you a detailed introduction to the characteristics of aircraft fasteners to help you better understand the aviation manufacturing industry.

High Strength

Aerospace fasteners must be strong enough to withstand the rigors of extreme conditions, such as high speed, high temperature, high pressure and vibration.

Corrosion Resistance

Aerospace fasteners must be able to resist corrosion caused by exposure to extreme temperatures, humidity, and other environmental contaminants.


Aerospace fasteners must be lightweight in order to minimize the overall weight of the aircraft.


Aerospace fasteners must be non-magnetic to prevent interference with the aircraft’s navigation and communication systems.

Low Friction

Aerospace fasteners must be able to resist friction caused by high speed and vibration.

Common Types of Aerospace Fasteners

Aerospace fasteners are an integral part of the aerospace industry, and they are available in a variety of sizes, thread types, and drive styles to meet the needs of any aerospace application. Here are some common fasteners examples including bolts, screws, studs, nuts and rivets.

  • Bolts: Bolts are the most common type of fastener used in aerospace applications. They are defined as a type of threaded fastener that requires a pre-drilled hole and a nut to secure two or more components together. Bolts are usually made of corrosion-resistant materials such as steel or aluminum alloys.

  • Nuts: Nuts are a type of threaded fastener that is typically used in conjunction with a bolt to secure two or more components together. Non-locking and self-locking airplane nuts are available. They are indispensable for aircraft that need to go through plenty of vibrations.

  • Rivets: Rivets are a type of fastener used to join two or more components together. They are typically made from aluminum or other metals and are inserted into pre-drilled holes and then formed or deformed to secure the components together.

  • Screws: The majority of fasteners used in aircraft structures are screws which also have exterior threads just like bolts, but they have a helical ridge. They are frequently constructed of lower-strength materials than bolts and inserted with a loose-fitting thread. In the construction of aircraft, many types of screws with various materials and designs are employed.

  • Studs: Studs are a type of fastener used to secure two components together in a single direction. They are typically used in applications where a component needs to be secured in a single direction, such as a propeller shaft or a rudder.

Besides, there are some special air fasteners examples.

  • Lockbolts: Lockbolts are a type of fastener that uses a two-piece assembly to secure two or more components together. The fastener consists of a threaded bolt and a pin that is inserted into a pre-drilled hole.

  • Blind Fasteners: Blind fasteners are used to join two or more components together in a non-visible manner. They are typically used in applications where access to the backside of the components is not possible.

The Materials of Aerospace Fasteners

Aerospace fasteners are typically made from a variety of materials, including aluminum, steel, titanium, bronze, nickel-based alloys, and so on. Each material has its own unique set of properties that make it suitable for different applications.

Aluminum is lightweight, strong, and corrosion-resistant. It is often used in aerospace components due to its strength-to-weight ratio and resistance to fatigue, making it ideal for the fuselage.

  • Steel

Steel is strong and durable, making it a popular choice for engines and other components that require a high level of strength. It is also highly resistant to corrosion and temperature extremes.

  • Titanium

Titanium is a lightweight and strong metal that is highly resistant to corrosion. Aluminum could be replaced with Titanium for making various fasteners for commercial airplanes. In terms of strength, the strength of titanium is not inferior to that of steel.

  • Superalloys

Superalloys are a class of materials that are typically used in high-temperature applications due to their excellent strength and corrosion resistance. They are made up of a combination of metals such as nickel, cobalt, and iron, and often include other elements like chromium, molybdenum, and tungsten. Superalloys are typically used in extreme industrial applications, such as jet engines, nuclear reactors, and oil and gas exploration. They are also used in medical devices and aerospace components. Superalloys have a wide range of applications due to their ability to withstand high temperatures and extreme conditions.


Aviation Quality Standards

Aviation quality standards refer to a set of regulations and procedures followed by the aviation industry to ensure the safety, reliability, and efficiency of aircraft and other aviation-related operations. Examples of aviation quality standards are as follows:

  • AS9100 and AS9120 standards: are widely used in the aviation industry.

  • AS9100, BA9100 and EN9100 standards: are followed by organizations creating and producing aerospace products, such as parts, components, and assemblies.

  • AS9120, BS9120, and EN9120 standards: are for people who produce or sell aviation parts, components, etc.


Aerospace Covers

The covers of fasteners are definitely needed to resist the harsh environmental conditions.The materials used to make those covers come in a wide range and have varying degrees of resistance to the various environmental situations encountered. Here are the materials used for aircraft fastener covers:

  • Zinc

  • Nickel

  • Cadmium

  • Silver

  • Black Oxide

  • Phosphate
