This standard is being maintained under Stabilized Maintenance. Stabilized maintenance is an option for maintenance of a standard that requires status review every 10 years rather than revision or reaffirmation every 5 years. The Standards Committee shall consider all requests and recommendations for change to standards maintained under the stabilized maintenance option from any materially affected and interested party. The request shall be made in writing and should include the rationale for the particular request in order to facilitate review by the Committee.

This Standard covers general specifications and dimensions for flat, round hole washers, both soft (as fabricated) and hardened, intended for use in general purpose applications. The inclusion of dimensional data in this Standard is not intended to imply that all sizes displayed are production stock items. Manufacturers should be contacted for current information on stock sizes.
