Full title and description

Prevailing torque type all‑metal hexagon high nuts with metric fine pitch thread — Property classes 8, 10 and 12 (ISO 10513:2012). This International Standard specifies the characteristics, dimensions and designation rules for all‑metal prevailing‑torque hexagon high nuts with metric fine pitch threads for nominal diameters from 8 mm to 36 mm.

Abstract

ISO 10513:2012 defines requirements for prevailing‑torque, all‑metal hexagon high nuts with metric fine pitch threads, covering nominal thread diameters D = 8 mm up to and including 36 mm; product grade A for sizes D ≤ 16 mm and grade B for sizes D > 16 mm; and property classes 8, 10 and 12. The standard references related ISO fastener standards for dimensions, tolerances and performance. The 2012 edition has since been superseded by a 2025 edition.

Scope

Specifies characteristics and designation for prevailing‑torque (all‑metal) hexagon high nuts with metric fine pitch threads, nominal thread diameters from 8 mm to 36 mm inclusive, covering property classes 8, 10 and 12 and product grades A and B as applicable by size. It also points users to related ISO standards for thread tolerancing, mechanical properties and testing when other or additional specifications are required.

Key topics and requirements

• Definition and designation of prevailing‑torque all‑metal hexagon high nuts (style 2) with metric fine pitch thread.
• Range of nominal thread diameters: 8 mm to 36 mm inclusive.
• Product grades and applicability: grade A for D ≤ 16 mm; grade B for D > 16 mm.
• Property classes covered: 8, 10 and 12 (mechanical strength classes).
• References to normative standards for thread form, tolerances, mechanical testing and surface treatments (examples: ISO 261, ISO 724, ISO 898‑2, ISO 2320, ISO 4759‑1, ISO 10683).
• Dimensional and designation rules for marking and ordering prevailing‑torque hexagon high nuts.

Typical use and users

Used by fastener manufacturers, procurement and quality assurance teams, mechanical and design engineers, OEMs and testing laboratories to specify, produce, inspect and order prevailing‑torque all‑metal hexagon high nuts for applications requiring a non‑metallic‑free prevailing torque feature (all‑metal locking action) in fine‑pitch metric assemblies. Users also consult the standard when harmonizing national or regional variants (EN, BS, UNE, DIN adoptions).

Related standards

Typical normative and related references include ISO 2320 (prevailing torque steel nuts — mechanical and performance properties), ISO 898‑2 (mechanical properties of nuts), ISO 261 and ISO 724 (metric thread dimensions), ISO 4759‑1 (tolerances and inspection), and ISO 10683 (zinc flake coatings). National/adopted EN versions (EN ISO 10513:2012) exist for regional application.

FAQ

Q: What is this standard?

A: ISO 10513:2012 is an International Standard that specifies the characteristics and designation of prevailing‑torque type all‑metal hexagon high nuts with metric fine pitch threads (nominal diameters 8–36 mm) and property classes 8, 10 and 12.

Q: What does it cover?

A: It covers dimensions, designation and basic requirements for all‑metal prevailing‑torque hexagon high nuts (style 2) with fine‑pitch metric threads, and points to other ISO standards for thread tolerancing, mechanical properties and testing.

Q: Who typically uses it?

A: Fastener manufacturers, design and mechanical engineers, OEM procurement and QA/inspection laboratories use the standard to specify, manufacture and verify prevailing‑torque nuts. National standards bodies and standards adopters (EN/BS/UNE/DIN variants) also reference it.

Q: Is it current or superseded?

A: The 2012 edition has been superseded. ISO 10513:2012 was withdrawn and replaced by ISO 10513:2025 (new edition). Records show the 2012 text listed as withdrawn when the 2025 edition was published.

Q: Is it part of a series?

A: It is part of the family of ISO fastener standards covering nuts and prevailing‑torque products and is intended to be used alongside related standards such as ISO 2320 and ISO 898‑2. Regional/adopted EN versions (EN ISO 10513) exist as part of harmonized fastener documentation.

Q: What are the key keywords?

A: Prevailing torque, all‑metal, hexagon high nut, fine pitch thread, property class 8/10/12, product grade A/B, ISO 10513.
