Understanding Types of Aircraft Fasteners

Aerospace Fasteners are used in aerospace applications. They are designed to resist the forces that pull two or more parts apart. This resistance is known as a shear force. If you have seen a bolt that will not move, it is likely a shear bolt.

Materials used in aerospace fasteners

Materials used in aerospace come in different shapes and sizes. For example, aluminum is commonly used in atmospheric planes but requires special treatment to prevent corrosion. On the other hand, titanium is also light and suitable for highly stressed components.

Another essential requirement is that aerospace fasteners be lightweight. Although titanium has been the dominant material in aerospace fasteners for the past 30 years, it does not work as well in high-temperature environments. Therefore, other materials, such as nickel-based alloys or multi-phase materials, may be used instead.

Turn-lock fasteners are one type of aerospace fastener. These fasteners have a head on one end of a cylindrical shaft. They are employed to join two pieces of metal. The shank of the rivet is inserted into matched holes on one or both material parts to form the rivet. The rivet tip then upsets and includes a second head, clamping the two pieces together. Washers, such as plain and lock washers, are another component of aerospace fasteners and are easily accessible at your local hardware distributors.

The function of a bolt

In the aerospace industry, fasteners are required for the safety of aircraft. These fasteners must be strong enough to hold together the components and withstand extreme pressures and temperatures. To produce the best aircraft fasteners, engineers use advanced technology and design. The aerospace industry also uses many materials in its components, including composites and metals.

Aerospace fasteners are also necessary for aircraft and spacecraft, as the aerospace industry relies on them to secure their bodies, panels, and wings. The type of fastener used depends on the kind of joint that needs to be confirmed. They can be used in pressurized or non-pressurized environments and transfer loads to support the structure. In addition, the fastener type affects the aircraft’s structural strength and weight.

The material and stiffness of the fastener also play a role in its function. Some materials cannot endure high-pressure environments, while others can deliver the demanding performance characteristics that aerospace fasteners require. For instance, titanium aerospace fasteners can withstand high temperatures and still maintain structural integrity of the structure. Furthermore, titanium aerospace fasteners can help reduce weight, which improves fuel efficiency.

Shear-off point

Shear-off points are critical for aerospace fasteners. These joints support loads through a tight fit. If a fastener does not fit tight enough, it can be avoided using specialized aerospace bolts and precision hole-making techniques.

Hi-Shear Corporation manufactures several types of aerospace fasteners. Its hi-Lok (TM) fastener is an example of this type.

A shear pin is a mechanical safeguard that shears out during mechanical overload. This helps to protect more expensive and less easily replaced parts. It is similar to an electric fuse. The most common use for a shear pin is in drive trains. Other applications include the auger on a snow blower or propellers attached to marine engines.

Fasteners can also be designed with a particular application in mind. For instance, Boeing fasteners come in several different versions, such as BACB30NJ and BACB30LJ. Other aerospace fasteners are NAS6620, NAS563, and NAS572, and torque is controlled by aircraft spec.

Applications

Aerospace fasteners are widely used in commercial aviation. This sector is growing with increasing demand for air travel. Airlines face challenges in maintaining their fleet and acquiring new aircraft. This, in turn, is driving the need for aerospace fasteners.

Aerospace fasteners come in a wide variety of types and specifications. Some are used in military and defense aircraft, while others are found in commercial airplanes and satellites. Fasteners used in aerospace engineering are known to have high tensile strength and can withstand high stress and vibration.

The global market for aerospace fasteners is highly segmented based on product, material, and application addition. In addition, it is further segmented based on region. The regional markets for aerospace fasteners are North America, Europe, Asia-Pacific, Latin America, and the Rest of the World.
