NAS1200 Specification – Flush Shear Head – Rivet Spec

Part Number: NAS1200, NAS1200-3

Function: Rivet, Solid, 100 DEG Flush Shear Head, A286 Corrosion Resistant Steel And Monel

Manufacturer: Aerospace Industries Association



A NAS1200 is Flush Shear Head Rivet. Rivets can be made from a variety of materials, including steel, aluminum, copper, and brass.

There are several types of rivets, including solid rivets, blind rivets, and tubular rivets.

A flush shear head rivet is a type of mechanical fastener that is commonly used in manufacturing, construction, and other industries. It is a type of blind rivet, which means that it can be installed from one side of the workpiece without access to the other side.

The flush shear head rivet consists of a cylindrical body with a mandrel or stem that passes through the center of the body. The mandrel is pulled through the body using a special tool, which causes the end of the mandrel to expand and create a bulge on the blind side of the workpiece. This bulge creates a permanent joint between the two workpieces.
