Compliance FAQs: Fastener Quality Act (FQA)

THIS CONTENT LAST UPDATED 11/15/2019. (NOTE: CONTENT MAY NOT BE THE MOST CURRENT.)

What is the Fastener Quality Act?

The enactment of the Fastener Quality Act (FQA) was the result of a number of high-profile fastener failures in the 1980s. An investigation by the Congressional Subcommittee on Oversight and Investigations found alarming shortcomings in industry standards, quality control and safety inspection. In addition they found that many overseas suppliers were supplying counterfeit safety certificates and passing off cheap parts as higher quality.

On November 16, 1990, the FQA, Public Law 101-592, was signed by President George H.W. Bush. The FQA was enacted to protect 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 FQA makes it a violation to knowingly falsify or misrepresent the record of conformance for the lot of fasteners; the identification, characteristics, properties, mechanical or performance marks, chemistry, or strength of the lot of fasteners; or the manufacturer's insignia.

Since its enactment, the FQA has been amended three times (Pub L. 104-113, Pub L. 105-234, and Pub L. 106-34) to further clarify and define the requirements of the original FQA.

The law and amendments has been codified at 15 USC 5401 et. seg. Regulations for implementing the FQA can be found at 15 CFR 280.

What types of fasteners are covered under the Act?

Fasteners covered under the FQA are defined as limited to metallic bolts, nuts, screws and studs (having a nominal diameter of 6 millimeters/0.25 inch or greater) or direct tension-indicating washers that are through-hardened (or meet a consensus standard that calls for through-hardening) and manufactured to standards and specifications of consensus standards organizations or government agencies that require a grade mark.

Many fasteners are exempted from coverage including those:

  • that are part of an assembly;
  • that are ordered for use as a spare, substitute, service or replacement part unless that part is in a package containing more than 75 of any such part at the time of sale or that part is contained in an assembly kit produced and marked as ASTM A 307 Grade A;
  • produced in accordance with the ASTM F 432 standard;
  • specifically manufactured for an aircraft if the quality is approved by the Federal Aviation Administration or by a foreign airworthiness authority;
  • manufactured in accordance with the International Organization for Standardization (ISO) 9000, 9001, 9002, or TS16949; Quality system (QS) 9000; or other fastener quality assurance system defined by law; or
  • manufactured to a proprietary standard.

To encourage the use of quality management systems such as QS 9000, fasteners are exempt from the FQA if they are manufactured in a facility using such a system. If an accreditation organization chooses not to follow ISO guidelines for registration and accreditation, they may submit documents to the NIST director that establish their own guidance/requirements for (1) accredited bodies to register manufacturing systems as meeting FQA quality assurance requirements; (2) accreditation of testing laboratories; and (3) approval of accreditation bodies to accredit testing labs.

What are the requirements of the FQA?

Testing to verify that a lot of fasteners conforms to the grade identification marking called for in the consensus standard or standards that the lot of fasteners has been manufactured must be done by an accredited laboratory.

A fastener is required by the applicable consensus standard(s) to bear an insignia identifying its manufacturer.  The manufacturer must:

  • Record the insignia with the U.S. Patent and Trademark Office (USPTO) prior to any sale or offer for sale of the fastener; and
  • Apply the insignia to any fastener that is sold or offered for sale.

The insignia must be readable, and must be permanent. 

The manufacturer must also create a record of conformance to demonstrate compliance to consensus standards or specifications.

What is required on the record of conformance?

The following are required to be on the record of conformance:

  • The name and address of the manufacturer
  • A description of the type of fastener
  • The lot number
  • The nominal dimensions of the fastener (including diameter and length of bolts or screws), thread form, and class of fit
  • The consensus standard or specifications to which the lot of fasteners has been manufactured, including the date, number, revision, and other information sufficient to identify the particular consensus standard or specifications being referenced
  • The chemistry and grade of material
  • The coating material and characteristics and the applicable consensus standard or specifications for such coating
  • The results or a summary of results of any tests performed for the purpose of verifying that a lot of fasteners conforms to its grade identification marking or to the grade identification marking the lot of fasteners is represented to meet

How long must I retain the record of conformance?

Manufacturers and importers must retain the record of conformance for fasteners for 5 years, on paper or in photographic or electronic format in a manner that allows for verification of authenticity. Upon request of a distributor who has purchased a fastener, or a person who has purchased a fastener for use in the production of a commercial product, the manufacturer or importer of the fastener must make information in the record of conformance available to the requester.

How do I submit an application for recordial of an insignia?

Each manufacturer must submit the

along with the prescribed fee, for recordal of an insignia on the Fastener Insignia Register. Instructions are in the Application PDF and more details are available on the USPTO Fastener Quality Act webpage. 

Once the new application is received the manufacturer will receive a Certificate of Recordal depicting the mark, the owner's information, and the date of recordal from which renewals are to be calculated.

How long is the certificate valid?

Certificates of recordal remain in an active status for five years. The certificate holder must file the prescribed maintenance fee and the maintenance application within six months prior to the expiration of each five-year period running consecutively from the date of issuance.

If the maintenance application is not filed in time, the certificate of recordal will be designated inactive. However, such certificate may be designated active if the certificate holder files the prescribed maintenance fee and application and the additional surcharge within six months following the expiration of the certificate of recordal.

After 6 months following the expiration date, the holder must file a new application along with the prescribed fee and a copy of the expired certificate.

How do I report fraudulent fasteners?

To combat the manufacture, sales or distribution of fasteners that are fraudulent under the FQA, NIST has established a hotline for reporting alleged violations of the law.  The FQA violation hotline can be reached at: 1-800-424-2980.  This hotline is only for reporting alleged violations, not for obtaining general FQA information.  Please fqa [at] nist.gov (email) us for general FQA information.

How are laboratories that are engaged in fastener testing accredited?

Laboratories that perform fastener testing must be accredited. The amended law no longer requires the Commerce Department’s National Institute of Standards and Technology (NIST) to approve organizations that accredit fastener testing laboratories.  Instead there is a self-declaration process that must be followed to demonstrate that they meet requirements of applicable standards or equivalant.

Self-Declaration Forms:

Where can I find a list of laboratory accreditation organizations that meet the requirements of ISO/IEC Guide 58?

In addition to the NIST laboratory accreditation program (NVLAP) and pursuant to 15 U.S.C. 5411a and 15 CFR 280.102, the following laboratory accreditation organizations have affirmed to NIST that they meet the requirements of ISO/IEC Guide 58 (or another document approved by the Director) and shall continue to meet such requirements. This acknowledgment of the accreditor's affirmation should not be construed as NIST approval/recognition of the accreditation organization or their accredited laboratories.
