This Standard outlines a Quality Assurance Plan for internally and externally threaded fasteners and accessories or associated parts. Provisions are included for sampling plans, inspection frequencies, control procedures, and record keeping. The basic structure of this plan outlines the quality assurance provisions for fasteners manufactured and processed using in-process controls. Included are fasteners produced by one manufacturing practice requiring records of in-process inspection and tests which are maintained by the producers. This Standard will be used in conjunction with other accepted standards for product, testing, gaging, and material, and, therefore, those provisions as well as packaging are not included herein.
