B18.11 - Minature Screws

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 establishes head types, their dimensions, and lengths of slotted head miniature screws, threaded in conformance with American National Standard unified miniature screw threads, ASME B1.10. This standard is predicated upon information derived through research of the maximum using industries. The inclusion of four head types and the given thread sizes in the data tables is not intended to imply that all of those described in this standard are stock production items. Preferred diameter pitch combinations for general use are shown in bold type in the tables. Consumer interests are requested to consult manufacturers’ catalogs for lists of current stock production miniature screws.
