This specification is intended to establish and control the quality of blind rivets for use in structural applications.

The specification establishes the requirements for procurement of self-plugging blind rivets, with a visual mechanically locked solid spindle, which can be installed in assemblies or construction. These blind rivets are intended for use in aircraft structural or similar applications in both thick and thin sheets. The bulbed blind head configuration makes these rivets especially suited for thin sheet or double dimpled applications.
