In aerospace projects, choosing the right fasteners is critical to ensuring the safety, strength, and durability of aircraft and aerospace equipment. With over 15 years of experience in the fastener industry, I’ll guide you through the most common fasteners used in aerospace projects, explaining their practical applications, typical sizes, and coatings. Whether you’re working on aircraft assembly, satellite installations, or aerospace repairs, this guide will help you understand which fasteners you need.
In aerospace projects, common fasteners include Threaded Rods, Nuts and Lock Nuts, Washers, and Hex Bolts. These fasteners are used to secure components like engines, landing gear, and airframes. Threaded Rods offer adjustable connections, while Nuts and Lock Nuts ensure tight security. Washers distribute load, and Hex Bolts secure heavy components. These fasteners are crucial for ensuring safety, strength, and durability in aerospace applications.

1. Common Materials for Aerospace Fasteners
Aerospace fasteners must be lightweight yet strong enough to withstand extreme conditions such as high altitudes, high speeds, and exposure to harsh temperatures. Here are the most common materials used in aerospace fasteners:
- Titanium: Titanium fasteners are highly valued in aerospace because of their high strength-to-weight ratio and resistance to corrosion, particularly in extreme conditions like high altitudes.
- Stainless Steel: Stainless steel is often used for aerospace fasteners due to its durability, rust resistance, and ability to withstand high temperatures.
- Aluminum: Lightweight yet strong, aluminum is often used for fasteners in non-critical parts of an aircraft or aerospace structure, where weight reduction is a key priority.
- Inconel: For extreme high-temperature applications, especially in engines and exhaust systems, Inconel fasteners are preferred due to their ability to withstand high heat without losing strength.
Let’s dive into the specific fasteners used in aerospace.
2. Common Fasteners Used in Aerospace Projects
2.1 Threaded Rods
Threaded Rods are long, cylindrical fasteners with threads running along their length. They are essential for adjustable connections in aerospace structures, such as aircraft engines, landing gear systems, and aircraft wings.
Threaded Rods are available in sizes typically ranging from 1/4 inch to 2 inches in diameter, with lengths that can extend several feet depending on the application. These rods are often used in critical connections that require high strength and flexibility, as they can be easily adjusted to fit different lengths or configurations.
In aerospace, they are used for high-stress connections in areas like engines and landing gear, where precise adjustments are necessary.
2.2 Nuts and Lock Nuts
Nuts and Lock Nuts are used to secure bolts in place, ensuring that fasteners do not loosen due to vibrations or movement. These fasteners are critical in aerospace projects where safety and stability are top priorities.
Lock Nuts, in particular, are designed to prevent loosening and are often used in environments exposed to frequent vibrations. These fasteners come in various sizes, typically ranging from 1/4 inch to 1 inch in diameter, and are used with bolts in a variety of aerospace applications.
In aerospace, they secure important components like engine parts, control systems, and airframe connections, ensuring that these elements stay securely in place under high-pressure conditions.
2.3 Washers
Washers are flat, ring-shaped fasteners that are placed between a nut or bolt and the surface being fastened. Their main purpose is to distribute the load of a fastener evenly and reduce friction during installation, ensuring a secure and long-lasting connection.
Washers are commonly used in aerospace to prevent damage to surfaces, improve the fit of fasteners, and prevent them from loosening. Common sizes for washers in aerospace applications range from 1/4 inch to 1 inch in diameter, depending on the size of the fastener.
They are used in engine components, landing gear, and fuselage connections to reduce wear and tear on the surface materials, ensuring that fasteners remain tightly in place over time.
2.4 Hex Bolts
Hex Bolts are strong fasteners used to connect heavy components in aerospace projects. They are designed to handle high loads and are used in critical structural connections, such as aircraft frames and engine mountings. Hex Bolts have a hexagonal head that allows them to be easily tightened or loosened with a wrench.
Made from high-strength alloys or stainless steel, Hex Bolts are available in sizes from 1/4 inch to 1 inch in diameter, with lengths from 1 inch to several inches depending on the application. These bolts are often coated with zinc or nickel to provide additional corrosion resistance.
In aerospace, Hex Bolts are essential for securing parts like aircraft wings, engine mounts, and fuselage components, where high strength and secure connections are critical.
