Which rivet type is known for being commonly used in aircraft structures?

The rivet type classified as MS20470D is widely utilized in aircraft structures primarily due to its specific design and mechanical properties, which make it suitable for high-strength applications. This rivet is a solid shank rivet made of aluminum alloy, and it is commonly used in aircraft because of its lightweight and corrosion resistance. The MS20470D rivet has a round head and is intended for use in structural applications, ensuring it meets the necessary strength and performance requirements that aircraft materials demand.

Other rivets mentioned, such as MS20470A, have different specifications or applications, while AN470 and AN426 rivets, although also used in aviation, serve different purposes and might not be as prevalent as the MS20470D when it comes to certain structural contexts within the airframe. The MS20470D rivet stands out for its versatility and effectiveness in providing secure and reliable joints, which is critical in maintaining the integrity of aircraft structures.
