Aerospace Fasteners: An Overview

In aerospace, every component counts. Aerospace fasteners—like screws, bolts, rivets, and collars—are no exception. These small parts play a big role in keeping aircraft safe and secure.

Screws and Bolts

Screws and bolts are the backbone of any assembly. In aerospace, they need to be strong yet lightweight. Companies like LISI Aerospace and AMI manufacture these components with high strength and close tolerance. They’re designed to handle the stresses of flight, from the pressure of takeoff to the vibrations of high-speed travel.

Rivets

Rivets are another key player in aerospace applications. They join parts permanently, providing a strong bond that can withstand the rigors of flight. Unlike screws and bolts, which can be removed, rivets are there to stay. This makes them ideal for parts of the aircraft that don’t need regular maintenance.

Collars

Collars are used to secure bolts and screws, ensuring they don’t loosen over time. In the aerospace industry, where even a slight movement can cause serious problems, collars are crucial. They provide an extra layer of security, keeping everything in place during a flight.

Aerospace Applications

In aerospace, every fastener must meet strict standards. Whether it’s holding together the fuselage of a commercial jet or securing components in a satellite, these parts must be reliable. They are often made from high-performance materials like titanium and aluminum alloys, which offer strength without adding unnecessary weight.

Aerospace Fasteners in Action:

• Commercial Jets: Used in airframes, wings, and engines.
• Defense Vehicles: Secure components in military aircraft.
• Spacecraft: Essential for satellite assembly and space exploration.

The precision and reliability of aerospace fasteners are non-negotiable. They ensure the safety of countless passengers and crew members every day. As technology advances, so do these tiny yet mighty components, adapting to new challenges and innovations in the aerospace industry.

Frequently Asked Questions about Aerospace Fasteners

What are the fasteners used in aerospace?

In the aerospace world, fasteners are the small but mighty heroes that keep everything together. They include screws, collars, bolts, anchors, and rivets. Each type of fastener has a specific role. For instance, screws and bolts are used for securing panels and components, while rivets are often used in places where welding isn’t suitable. Collars, on the other hand, are typically used in conjunction with bolts to provide extra security.

What are the five basic fasteners?

Fasteners come in many shapes and sizes, but the five basics you should know are:

1. Screws – These are versatile and can be used for a variety of purposes, from securing panels to joining components.
2. Nails – Common in construction, but less so in aerospace due to the need for more precision.
3. Bolts – Used for assembling parts that need to be disassembled or adjusted.
4. Anchors – These provide support for fasteners in materials that are too brittle to hold them by themselves.
5. Rivets – Often used in aircraft construction for permanent fastening where welding is impractical.

What grade are aerospace bolts?

Aerospace bolts must withstand extreme conditions and stresses. That’s why they are graded for strength and durability. In aerospace, common bolt grades include Grade 5, Grade 8, and Grade BD.

• Grade 5 bolts are made of medium carbon steel and are heat-treated for increased strength. They are suitable for applications that require moderate strength.
• Grade 8 bolts are stronger, made from alloy steel, and are also heat-treated. They are used in high-stress applications.
• Grade BD bolts are even tougher, often used in critical aerospace applications where safety and reliability are paramount.

These grades ensure that aerospace fasteners can handle the pressures and stresses of flight, keeping aircraft secure and operational.
