GOST R 52643-2006 PDF

Full title and description

GOST R 52643-2006 — "Болты и гайки высокопрочные и шайбы для металлических конструкций. Общие технические условия" (English: High‑strength bolts, nuts and washers for metal structures — General specifications). This national Russian standard sets general technical requirements for high‑strength hexagon bolts, high‑strength hexagon nuts with increased wrench size and washers intended for use in structural metalwork in construction and machinery.

Abstract

This standard defines material, dimensional, mechanical and testing requirements, marking, packaging and acceptance rules for high‑strength bolting components used in metal structures (including bridges and building frameworks). It incorporates requirements on coatings, surface condition and specific test methods (including torque/tightening coefficient tests) and references related national and international fastener standards.

General information

• Status: Withdrawn / cancelled for use in Russia (note: users are directed to newer series standards such as the ГОСТ 32484.* series for high‑strength bolt assemblies).
• Publication date: Approved 27 December 2006 (Order No. 408‑st); introduced into effect 1 January 2008.
• Publisher: Approved by the Federal Agency on Technical Regulation and Metrology (Rosstandart); printed/issued by Standartinform (official edition).
• ICS / categories: OKS/ICS 21.060.01 (Fasteners).
• Edition / version: Original designation GOST R 52643‑2006 (with at least one published amendment).
• Number of pages: Published edition — approximately 27 pages (official print edition information).

Scope

Applies to high‑strength hexagon head bolts, high‑strength hexagon nuts with increased wrench size and plain washers intended for structural connections in construction (including bridge construction) and mechanical engineering. The standard covers products used across macroclimatic regions (moderate and cold climates) and references national climate classification (GOST 15150). It is concerned with requirements for materials, mechanical properties, dimensional tolerances, protective coatings and specified test methods for conformity assessment.

Key topics and requirements

• Definitions and product designation for high‑strength bolts, nuts and washers.
• Material and mechanical property requirements (property classes, tensile and yield related requirements consistent with referenced ISO/GOST mechanical standards).
• Dimensional and tolerance requirements (including increased wrench sizes for nuts and specific washer types).
• Surface condition and protective coatings (zinc and other coatings) and test methods for coating control.
• Acceptance rules, sampling plans and test procedures (including torque/tightening coefficient tests described in Appendix E and sampling per referenced GOST R ISO methods).
• Marking, packaging and documentation requirements for traceability and use in structural applications.

Typical use and users

Used by structural engineers, steel fabricators, fastener manufacturers, quality and inspection laboratories, bridge and building contractors, and regulatory authorities involved in specification, procurement and conformity assessment of high‑strength structural bolting assemblies. It was intended as a national normative reference for designers and manufacturers specifying bolted connections in metal structures.

Related standards

References and related documents include ISO 7411, ISO 7415, ISO 4775 and several national GOST/GOST R fastener standards (for example GOST R 52627‑2006, GOST R 52628‑2006). For contemporary use in Russia the EN/ISO‑based series ГОСТ 32484.1–32484.6 (based on EN 14399) covers high‑strength bolt assemblies for pre‑tensioned structural connections and is the recommended reference following withdrawal.

FAQ

Q: What is this standard?

A: GOST R 52643‑2006 is a Russian national standard that specified general technical requirements for high‑strength bolts, nuts (with increased wrench size) and washers used in metal structural connections.

Q: What does it cover?

A: It covers material and mechanical requirements, dimensions and tolerances, protective coatings, test methods (including torque/tightening coefficient tests), acceptance rules, marking and packaging for structural fasteners.

Q: Who typically uses it?

A: Structural and design engineers, manufacturers of high‑strength fasteners, construction and bridge contractors, inspection laboratories and procurement specialists specifying structural bolting.

Q: Is it current or superseded?

A: It has been withdrawn/cancelled for use (its period of validity ended — effective date of termination reported as 1 July 2018) and users in Russia are directed to the ГОСТ 32484.* series (EN 14399‑based) and other current national/international standards for high‑strength bolt assemblies. Exact status notices and replacement guidance are published in national information indexes.

Q: Is it part of a series?

A: GOST R 52643‑2006 is a standalone national standard for general specifications of structural high‑strength bolts and related parts, but it references and works alongside other fastener standards (GOST R 52627, GOST R 52628, related ISO documents). Its practical role for structural bolt assemblies has since been taken by the multi‑part ГОСТ 32484.* series.

Q: What are the key keywords?

A: High‑strength bolts, nuts, washers, structural fasteners, torque coefficient, coatings, GOST R, structural connections.
