Marketplace Requirements:

Because the unit cost of fasteners is very low relative to the administrative and overhead costs to manage the supply of fasteners to the assembly line, OEMs have sought to reduce their total cost of purchasing and handling fasteners by shifting inventory, inspection, and engineering burdens to their distributors. As a result, distributors need to develop world-class capabilities to take over these functions efficiently. In many cases, the entire scheduling and inventory control process becomes vendor-managed.

Fastener distributors refer to Fastener Quality Act because it requires that certain fasteners sold in commerce conform to the specifications to which they are represented to be manufactured, to provide for accreditation of laboratories engaged in fastener testing, to require inspection, testing, and certification, in accordance with standardized methods, of fasteners used in critical applications to increase fastener quality and reduce the danger of fastener failure, and for other purposes.

The Fastener Quality Act, Public Law 101-592, was signed by President Bush on November 16, 1990. The Act protects the public safety by: (1) requiring that certain fasteners sold in commerce conform to the specifications to which they are represented to be manufactured, (2) providing for accreditation of laboratories engaged in fastener testing, and (3) requiring inspection, testing and certification in accordance with standardized methods.

The Act requires the Secretary of Commerce, acting through the Director of NIST, to establish a laboratory accreditation program for fastener testing laboratories under the procedures of the National Voluntary Laboratory Accreditation Program (NVLAP). The accreditation program includes test methods which are required by fastener specifications or standards covered by the Act. Since fastener testing involves a wide range of expertise, accreditation will be offered in the areas of mechanical and physical testing and inspection, metallography, nondestructive inspection, dimensional inspection, and chemical analysis.

On March 7, 1996, President Clinton signed the National Technology Transfer and Advancement Act of 1995, Public Law 104-113, which amended the Fastener Quality Act to further clarify and define the requirements of the original Act.

Inspection and Quality Assurance for General Purpose Fasteners

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. included in this plan are fasteners for general purpose applications, such as those where hand assembly is employed and cost is probably of prime consideration. this plan relies on judicious manufacturing controls and inspections by the producer and, should a dispute arise, provides an inspection plan for lot compliance after shipment. this standard will be used in conjunction with other accepted standards for product, testing, gauging, and material and, therefore, those provisions as well as packaging are not included herein.
