Full title and description

ISO 4034:2012 — Hexagon regular nuts (style 1) — Product grade C. This International Standard specifies the characteristics and dimensional requirements for hexagon regular nuts of style 1 in product grade C (metric threads M5 up to and including M64).

Abstract

ISO 4034:2012 defines the form, key dimensions and tolerances for hexagon regular nuts (style 1) in product grade C and covers thread sizes from M5 through M64. The edition includes a corrigendum (ISO 4034:2012/Cor 1:2013) and the published document is now withdrawn.

General information

• Status: Withdrawn (stage: Withdrawal of International Standard [95.99]; effective withdrawal documented in mid‑2021 — sources show effective date entries such as 22 June 2021 and withdrawn-from-sale listings in July 2021).
• Publication date: 13 December 2012 (Edition 4, 2012).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 21.060.20 (Nuts / Fasteners).
• Edition / version: Edition 4 (2012). Corrigendum ISO 4034:2012/Cor 1:2013 applies to the French version.
• Number of pages: 5 pages.

Scope

ISO 4034:2012 specifies the characteristics (including dimensions and tolerances) of hexagon regular nuts (style 1) in product grade C for metric coarse‑pitch threads from M5 up to and including M64. It is intended for general‑purpose fastening applications and refers to other ISO fastener standards for complementary specifications. Note: the standard itself has been withdrawn; consult current ISO fastener standards for up‑to‑date requirements.

Key topics and requirements

• Dimensional definitions and limits for hexagon regular nuts (style 1): across‑flats (s), across‑corners (e), nut height (m) and minimum internal thread requirements.
• Thread size range covered: M5 through M64 (metric coarse pitch).
• Product grade C classification — general product grade specifying tolerances and inspection acceptance for a general‑purpose nut category.
• Normative and informative cross‑references to related fastener standards (for example ISO 724, ISO 898‑2, ISO 3506‑2 and other ISO nut/bolt standards) for material, mechanical properties and alternative specifications.
• Notes on national/adopted equivalents and corrections (corrigendum issued in 2013 for the French text).

Typical use and users

Used historically by fastener manufacturers, mechanical designers, procurement teams, quality inspectors and standards bodies to specify and manufacture hexagon regular nuts in product grade C for general engineering applications. With the withdrawal of ISO 4034:2012, users should reference current ISO fastener standards or national adoptions for up‑to‑date requirements.

Related standards

ISO 4034 is part of the ISO fasteners family. Related and neighboring standards include ISO 4032 (hexagon regular nuts — product grades A and B), ISO 4035 (hexagon thin nuts chamfered, style 0), ISO 8673 / ISO 8674 / ISO 8675 (fine‑pitch variants and high nuts), ISO 898‑2 (mechanical properties of nuts) and other coating and finishing standards (ISO 4042, ISO 10683, ISO 10684). For current published replacements and revisions see ISO 4032:2023 and other active ISO fastener standards.

FAQ

Q: What is this standard?

A: ISO 4034:2012 is an International Standard titled "Hexagon regular nuts (style 1) — Product grade C" that defined dimensional and characteristic requirements for hexagon regular nuts in product grade C.

Q: What does it cover?

A: It covered the dimensions, tolerances and basic defining characteristics for hexagon regular nuts (style 1) with metric coarse‑pitch threads from M5 to M64, intended as a general‑purpose (grade C) specification.

Q: Who typically uses it?

A: Fastener manufacturers, design engineers, procurement/specification teams and quality/control personnel used the standard to ensure interchangeability and conformity of hexagon nuts in engineering applications. With the withdrawal, these users should consult current ISO fastener documents or national adoptions.

Q: Is it current or superseded?

A: ISO 4034:2012 is withdrawn (withdrawal stage 95.99, mid‑2021). Its withdrawal does not necessarily mean a direct one‑to‑one replacement under the same number; users are advised to refer to the current ISO fastener standards (for example ISO 4032:2023 covers hexagon regular nuts — product grades A and B) and applicable national/adopted equivalents for up‑to‑date specifications. Documented withdrawal entries and replacement activity were recorded in 2021 and later revisions to related documents were published (see ISO 4032:2023).

Q: Is it part of a series?

A: Yes — ISO 4034 belongs to the suite of ISO fastener standards covering hexagon nuts, thin nuts, high nuts and fine‑pitch variants (ISO 4032, ISO 4035, ISO 8673/8674/8675, ISO 898‑2, etc.), which collectively address dimensions, mechanical properties and specialized nut types.

Q: What are the key keywords?

A: Hexagon regular nut; style 1; product grade C; metric threads; M5–M64; dimensions; tolerances; fasteners; ISO 4034.
