A Comprehensive Overview of Aircraft Fasteners Types
Aerospace fasteners are one of the most underestimated components in the aviation sector. They may not be in the spotlight, but they are essential in keeping an aeroplane in the air. An interesting fact to underline this point: an aeroplane contains around 1 million aviation fasteners! We can enjoy this fastener debate even more now that we understand their importance. In this post, we'll look at several types of aircraft fasteners and their needs.
What Are Aerospace Fasteners?
Aerospace fasteners play a significant role in holding various aircraft body components together. Their job is critical, not just for performance but also for passenger safety. Consider the catastrophic consequences if one of the engines fails or a door opens in mid-flight; negligence is not an inexpensive luxury for aerospace engineers, even with fasteners!
The aerospace business produces various products, including commercial aeroplanes, military aircraft, spacecraft, and missile technology. As a result, aeroplane fasteners cover a wide range of uses.
Furthermore, they must be mainly developed for the demanding and diverse settings in which they function, and they differ significantly from the standard fasteners we are used to. We will go over all of these things in depth now.
Characteristics of Aerospace Fasteners
Aerospace or aviation fasteners must be solid to withstand significant gravity stresses. They are vital components that affect the aircraft's overall safety and efficiency. Furthermore, these fasteners must meet high certification standards to maintain efficiency in manufacturing and usage.
These fasteners are helpful in any equipment that requires high-precision and high-quality attachment. Here are some of the most typical characteristics of these fasteners:
Operates in harsh situations
High shear, fatigue, and tensile strength
Self-sealing and self-locking capabilities
High corrosion and oxidation resistance
Lightweight design
Common Types of Aircraft Fasteners
Some aerospace fasteners have a wide range of uses in commercial aircraft. Also included is an explanation of the various types of aviation fasteners and how they compare and vary.
Aircraft bolts: These are constructed from unplated corrosion-resistant steel, zinc-plated corrosion-resistant steel, cadmium, or anodised aluminium alloys. Furthermore, typical aviation bolts are MS bolts, close tolerance bolts, NAS internal twisting, and AN bolts.
Aircraft nuts: These threaded fasteners are constructed from cadmium-plated carbon steel, anodised 2024T aluminium alloy. Furthermore, they are usually used in tandem with a corresponding bolt or screw. There are two types of aviation nuts: self-locking and non-locking.
Aircraft screws: These fasteners are the most popular thread fastening type, with a helical ridge known as an external thread. They are frequently made of weaker materials than bolts and inserted with a loose-fitting thread.
Aircraft rivets: These fasteners feature a smooth cylindrical shaft with a head at one end and connect two or more metal sheets, plates, or pieces of material. The rivet's shank is inserted into matching holes in two pieces of material, and the tip is twisted to form a second head that firmly clamps the two pieces together.
Aerospace Collars (Lock Bolt Rivet): These fasteners work perfectly with lock bolt rivets (available separately). They help secure the rivet or bolt to the item and have bodies of matching metal alloy.
Aviation Quality Standards
The AS9100 and AS9120 quality management standards are widely used in the aerospace industry. AS9100, BS9100, and EN9100 are standards for enterprises that develop and manufacture aerospace components, parts, and assemblies. AS9120, BS9120, and EN9120 are standards for aircraft component manufacturers and distributors.
