Fastener Quality Act — Federal Standards for Bolts, Nuts, and Screws

The Fastener Quality Act (FQA), enacted in 1990 and amended in 1996 and 1999, establishes federal standards to ensure that fasteners — bolts, screws, studs, nuts, and related hardware items — used in critical applications are manufactured to the specifications they claim to meet. The Act and its implementing regulations at 15 CFR Part 280 address the problem of counterfeit and substandard fasteners: hardware stamped with high-strength grade marks that have been adulterated, improperly heat-treated, or fabricated from inferior materials, then sold as meeting aerospace, structural, or industrial standards they do not actually satisfy.

Legal Authority

• 15 U.S.C. § 5401 et seq. — Fastener Quality Act: establishes federal standards for fasteners sold in commerce; requires that fasteners meet the specifications they purport to meet; prohibits sale of misrepresented fasteners; authorizes civil and criminal penalties
• 15 CFR Part 280 — NIST regulations implementing the FQA; establishes accreditation requirements for fastener testing laboratories, lot-testing protocols, recordkeeping requirements, and enforcement procedures

Key Mechanics

The FQA addresses a specific supply chain integrity problem: counterfeit or substandard fasteners stamped with genuine-looking grade markings (A325 structural bolt markings, aerospace AS specifications) that are sold as meeting standards they don't actually satisfy. Under the Act, manufacturers and importers of fasteners with grade marks must have their products tested by accredited laboratories and maintain testing records for 5 years. Recordkeeping requirements ensure traceability — when a fastener fails in a bridge, aircraft, or manufacturing setting, investigators can trace back through the supply chain to identify the manufacturer. NIST accredits fastener testing labs under its National Voluntary Laboratory Accreditation Program (NVLAP); only NVLAP-accredited labs can perform required testing. Civil penalties up to $25,000 per violation apply to FQA violations; criminal penalties apply to knowing violations.

Current Rule (2026)

What This Rule Does

The FQA targets a specific commercial fraud problem: fasteners sold with counterfeit grade marks indicating compliance with industry standards (SAE, ASTM, ISO, ASME) that the fasteners do not actually meet. When a bolt stamped "Grade 8" (the highest common-use commercial strength grade) is actually made from low-carbon steel without proper heat treatment, the difference isn't visible but the consequences can be catastrophic — aircraft structural failures, bridge collapses, industrial equipment disintegrations.

The Act's approach is primarily a marking and representation system: it prohibits misrepresentation of fastener specifications, establishes a voluntary registry for fastener grade marks (the NIST Insignia List), requires independent laboratory testing and certification for certain classes of fasteners, and provides enforcement tools for NIST and DOJ. The 1996 and 1999 amendments substantially narrowed the original 1990 version's scope — eliminating mandatory testing requirements for most commodity fasteners — after industry objections that the full 1990 regime would be administratively unworkable.

Key Provisions

• § 280.1 — Scope and delegation: Part 280 implements the FQA under NIST authority; the FQA covers fasteners that are sold or distributed in commerce that are represented to meet a consensus standard, a government standard, or a manufacturer's standard; "fastener" means any metallic nut, bolt, screw, stud, headed stud, and related product that is 0.25 inch or larger in diameter and meets other dimensional thresholds specified in the Act
• § 280.101 — Petitions for document approval: a person may petition NIST to approve a document (testing standard, certification scheme, or quality system standard) for use in the FQA compliance framework; approved documents are published and available as references for manufacturers and customers
• § 280.102 — Affirmations by accreditation bodies: accreditation bodies that accredit entities to certify manufacturing quality assurance systems under the FQA must file affirmations with NIST confirming that they meet competency standards; NIST maintains a list of accreditation bodies that have filed valid affirmations
• § 280.103 — Laboratory accreditation: any laboratory that performs testing required under the FQA must be accredited by a NIST-recognized accreditation program; accreditation ensures that testing methodology and results are reliable; NIST maintains a list of accredited laboratories; using a non-accredited laboratory's test results to certify FQA compliance is a violation
• §§ 280.200–280.201 — Prohibited conduct: no person may (a) misrepresent the grade, certification status, heat number, lot number, or origin of any fastener; (b) falsify test results or certification records for fasteners; (c) offer for sale or sell any fastener that does not conform to the specification, standard, or testing requirement for which it was represented as meeting; (d) alter, deface, or remove any grade marking or lot identification on a fastener; (e) apply a grade mark to a fastener that does not comply with the applicable specification
• §§ 280.200–280.222 — Enforcement subpart: NIST's enforcement tools include (a) civil injunctive relief through DOJ action in federal court; (b) administrative enforcement proceedings before an administrative law judge (conducted under OEE procedures, despite OEE being associated with export enforcement — a delegation artifact of DOC's organizational structure); (c) civil money penalties; (d) criminal penalties under 15 U.S.C. § 5411 for knowing violations
• Subpart D — Insignia Recordal: manufacturers may register their proprietary grade marks (manufacturer-specific insignia impressed on fastener heads) with NIST's Insignia List; recordal puts the industry and enforcement community on notice of the legitimate manufacturer's mark; counterfeit fasteners bearing recorded insignia provide a clearer basis for FQA enforcement action than unmarked fasteners; recordal is voluntary

How It Affects You

If you're a fastener manufacturer: the FQA's core requirement is simple — don't sell fasteners that misrepresent their specifications. If you apply an ASTM A325 grade mark to high-strength bolts, those bolts must meet the ASTM A325 specification. If you use independent certification to support your grade claims, the certifying lab must be accredited and the QA system must be affirmed by a NIST-recognized accreditation body. The 1999 amendments significantly reduced the paperwork burden by eliminating most mandatory testing requirements for commodity fasteners.

If you're a purchasing manager, contractor, or engineer: the FQA creates legal protections and practical procurement tools. Fasteners bearing legitimate grade marks come with legal backing — sellers who misrepresent specifications face federal enforcement. For critical applications (structural, aerospace, pressure systems), consider requiring certified test reports traceable to an accredited laboratory, and verify that grade marks correspond to NIST's Insignia List records. The FQA doesn't eliminate counterfeiting, but it provides the enforcement framework for NIST and DOJ to act.

If you're in aerospace or defense procurement: the FQA is the baseline; more rigorous requirements under FAR/DFARS typically require documented material traceability, first-article testing, and certified test reports (CTRs) beyond FQA minimums. The FQA's laboratory accreditation requirement is particularly important — defense and aerospace contracts often specify NAVAIR or NADCAP-accredited testing, which satisfies the FQA accreditation requirement while meeting additional sector-specific standards.

Statutory Authority

This rule implements:

• 15 U.S.C. § 5401 — Congressional findings and purpose: acknowledges that substandard fasteners pose safety risks and that a uniform federal standard is needed to prevent misrepresentation in fastener commerce
• 15 U.S.C. § 5402 — Definitions: defines "fastener," "applicable standard," "conformance," "insignia," and other key terms
• 15 U.S.C. § 5403 — Scope: specifies what fasteners are covered (by size, type, and whether they bear grade marks)
• 15 U.S.C. § 5411 — Penalties: civil penalties up to $25,000 per violation as enacted (subject to annual inflation adjustment under the Federal Civil Penalties Inflation Adjustment Act; approximately $60,000+ per violation in 2026); criminal penalties for knowing violations (imprisonment up to 5 years)
• 15 U.S.C. § 5412 — Enforcement: Attorney General may seek civil injunctive relief; NIST may conduct inspections

Recent Rulemakings

The implementing regulations were substantially revised after the 1999 FQA amendments (65 FR 39801, June 28, 2000), which removed the original 1990 Act's mandatory testing and certification requirements for most fasteners. The current framework relies primarily on anti-misrepresentation enforcement and voluntary laboratory accreditation rather than mandatory pre-sale testing — a significant deregulatory change reflecting the difficulty of applying comprehensive testing requirements to a commodity market measured in billions of individual fasteners annually.

No significant amendments since 2000.

Pending Action

No active rulemakings. Enforcement actions for FQA violations are brought by DOJ on NIST referrals.
