The NAAMS Global Standard Components for Assembly and Stamping initiative began under the sponsorship of the Auto/Steel Partnership in 1992.

The Stamping Cost Reduction Group was chartered to address cost reduction for stamping die components. Furthermore, the Assembly Cost Reduction Group was chartered to address cost reduction for the components in the tools used to fabricate sheet steel bodies-in-white, front-end sheet steel, and closures.

After several years, the names of these initiatives were changed to Stamping Tooling Standardization and Assembly Tooling Standardization to better reflect the aim of reducing cost without compromising quality or performance through standardization.

At some point, the Stamping initiative adopted the name North American Automotive Metric Standards (NAAMS).

In January 1995, the Stamping standards were first published on behalf of the A/SP by the Auto Industry Action Group (AIAG) under the title “North American Automotive Metric Standards - Forming & Stamping”.

The standards immediately gained wide acceptance in North America; however, it was reported that some automotive companies experienced resistance due to the words ‘North American’ in the title. As a result, the names were subsequently changed to:

  • NAAMS Global Standard Components – Stamping
  • NAAMS Global Standard Components - Assembly

NAAMS Global Standard Components for Assembly and Stamping is produced and maintained through collaboration efforts between Chrysler LLC., Ford Motor Company, General Motors Company, and their respective suppliers. They describe and define approved components utilized to design and manufacture Stamping Dies and Tooling to produce or join various sheet metal products as part of the vehicle body, assembly production process.
