Description
The MS20470 Rivet is the most common fastener used in the aircraft structuralassembly. The two initial letter in the part number identifies the standard, is military-Military Standard. The number 20470 identifies the geometry of the rivet, in this case: universal head. The head is like mushroom head.The identification part number presents one or two additional letters after the standard and geometry.
A military universal head solid rivet is a specific type of rivet used in military and aerospace applications. Rivets are mechanical fasteners that join two or more materials together by forming a permanent connection. They consist of a cylindrical shaft with a head on one end and a tail on the other.
The “universal head” refers to a specific rivet head design. The universal head has a flat top surface with a slightly rounded profile, providing a larger bearing surface when the rivet is installed. This design distributes the load more evenly, which can be beneficial for applications where strength and load-bearing capacity are critical, such as in military and aerospace structures.
This letters identifies the material of the rivet. Hard 2117 aluminum alloy. Heat treated with a minimum tensile strength of 38,000 PSI. Rivet, solid universal head, aluminum alloy and titanium columbium alloy , Military Specification.
Military universal head solid rivets are commonly used in aircraft manufacturing, shipbuilding, armored vehicle construction, and other military applications where high structural integrity and reliability are paramount. They offer advantages such as excellent shear strength, resistance to vibration and fatigue, and the ability to withstand harsh environmental conditions.
