MS20470A3-8 Solid Rivet is a military standard aircraft structural fastener designed for permanent joining of aerospace sheet metal components and structural assemblies. Supplied as a 1 lb package, these solid rivets are commonly used in aircraft manufacturing, maintenance, repair, and overhaul applications where high-strength, reliable fastening is required.

Manufactured in accordance with the MS20470 specification, this rivet features a universal head design identified by the A designation and is intended for installation by forming the tail of the rivet to create a permanent mechanical joint. The solid construction provides excellent shear strength and durability, making it suitable for primary and secondary aircraft structural applications.

Solid rivets are widely used in aircraft fuselage structures, wing assemblies, fairings, brackets, and other airframe components where resistance to vibration, fatigue loading, and operational stresses is essential. Proper installation requires the correct tooling, hole preparation, and inspection procedures to ensure the finished riveted joint meets aircraft structural requirements.

During maintenance inspections, riveted joints should be checked for looseness, deformation, corrosion, cracking, or other indications of structural damage. Replacement of damaged rivets helps maintain the strength and integrity of the aircraft structure.
