The MS20470AD6-16 is a universal head solid aircraft rivet made from 2117-T4 aluminum alloy (AD series), designed for structural sheet metal assembly in aircraft fuselage, wing, and airframe construction. The “6” indicates a 3/16" diameter, and the “-16” dash number corresponds to a 1-inch length, making it one of the longer grip rivets in this series.

This rivet is used in thicker material stacks where additional grip length is required to properly form a correct shop head during bucking. Compared to shorter variants like -8, -10, or -12, the -16 provides greater material engagement and is typically selected for multi-layer structural joints or thicker aircraft skins and assemblies.

It is installed using a rivet gun and bucking bar, requiring access to both sides of the structure. Proper selection of grip length is critical—too short results in insufficient shop head formation, while too long can cause buckling or “smiley face” deformation.
