ISO 7040:2012 specifies the characteristics of prevailing torque type hexagon regular nuts (with non-metallic insert) with threads from M3 up to and including M36, in product grade A for threads up to and including M16 and product grade B for threads above M16, and with property classes 5, 8 and 10.

Overview

ISO 7040:2012 defines the characteristics of prevailing torque type hexagon regular nuts (with non‑metallic insert). It covers metric threads from M3 to M36, in property classes 5, 8 and 10, and specifies product grade A for threads up to M16 and grade B for threads above M16. Dimensions correspond to ISO 4032 plus the locking (insert) system.

Keywords: ISO 7040, prevailing torque nuts, hexagon regular nuts, non‑metallic insert, nylon insert nuts, property class 5 8 10, metric threads M3–M36.

Key topics and requirements

Scope: Prevailing‑torque hexagon regular nuts with a non‑metallic insert (e.g., polyamide as an example material for the ring) for threads M3–M36.

Property classes: 5, 8 and 10 - mechanical performance categories referenced to ISO 898‑2 and ISO 2320 where applicable.

Product grades: Grade A for D ≤ M16, Grade B for D > M16 (tolerances described in ISO 4759‑1).

Thread tolerance: 6H for internal threads.

Dimensions: Follow ISO 4032 as the baseline; ISO 7040 adds the locking‑ring geometry (see figure and table in the standard).

Materials and surface finishes: Nut body typically steel; insert examples include polyamide. Coating and finish requirements are referenced to ISO 4042 (electrolytic) and ISO 10683 (non‑electrolytic zinc flake).

Inspection and acceptance: Reception and sampling per ISO 3269; surface defect limits per ISO 6157‑2.

Designation example: “Hexagon regular prevailing‑torque nut ISO 7040 - M12 - 8”

Applications and users

Practical uses of ISO 7040 prevailing‑torque nuts include assemblies requiring vibration resistance and reusable locking (where a non‑metallic insert provides prevailing torque). Typical sectors and users:

Fastener and component manufacturers specifying production dimensions and tolerances

Design and mechanical engineers selecting locking nuts for machinery, automotive, rail, construction and industrial equipment

Procurement professionals ensuring compliance with specified property classes and grades

Quality and inspection teams performing acceptance checks and surface/coating verification

Maintenance teams choosing compatible replacement fasteners with predictable locking performance

Related standards

ISO 7040 cross‑references and complements several ISO documents:

ISO 4032 (hexagon regular nuts dimensions)

ISO 261 / ISO 724 / ISO 965‑2 (metric thread standards)

ISO 898‑2 and ISO 2320 (mechanical properties and performance)

ISO 4759‑1 (tolerances: grades A, B)

ISO 4042, ISO 10683 (coatings)

ISO 3269 (reception inspection)

ISO 6157‑2 (surface defects)

Use ISO 7040:2012 when you need standardized prevailing‑torque hexagon nuts with a non‑metallic insert and clear rules for dimensions, tolerances, material references and inspection - ensuring interchangeability and consistent locking performance across designs.
