Overview
ISO 10511:2012 defines the characteristics of prevailing torque type hexagon thin nuts (with non‑metallic insert). It covers metric threads from M3 to M36, specifies product grades and property classes, and aligns nut dimensions with ISO 4035 while adding the prevailing‑torque feature. This International Standard is intended for use where a thin hexagon nut with an inserted, self‑locking (prevailing torque) function is required.
Key topics and requirements
- Thread range: M3 up to and including M36.
- Product grades: Grade A for threads up to and including M16; grade B for threads above M16.
- Property classes:04 and 05.
- Dimensions: Correspond to ISO 4035 (hexagon thin nuts) with added prevailing torque feature; figure and table of dimensional limits are given in the standard.
- Materials: Nut body - steel; insert - e.g., polyamide (non‑metallic).
- Thread tolerance: Class 6H (referenced ISO 261, ISO 724, ISO 965‑2).
- Mechanical and performance references: ISO 898‑2 and ISO 2320 for mechanical/property and prevailing torque performance.
- Coating and finish: Electroplating per ISO 4042; non‑electrolytically applied zinc‑flake coatings per ISO 10683; additional finishes agreed between supplier and purchaser.
- Quality and inspection: Surface discontinuity limits (ISO 6157‑2) and acceptance inspection (ISO 3269).
- Designation example: Prevailing torque type hexagon thin nut ISO 10511 - M12 - 04
Applications and who uses this standard
ISO 10511 is used by:
- Fastener manufacturers producing metric prevailing‑torque thin hex nuts with non‑metallic inserts.
- Design and mechanical engineers specifying self‑locking nuts in assemblies where a low‑profile (thin) nut is required.
- Procurement and quality assurance teams for specifying acceptance, coatings, and product grades.
- Test labs and inspectors performing acceptance inspection and verifying conformity to dimensional, material and performance requirements.
Typical practical applications include assemblies requiring a locking thin nut for vibrational resistance or where space constraints favor a low‑profile hexagon nut with self‑locking capability.
Related standards
Relevant referenced standards include:
- ISO 4035 (hexagon thin nuts dimensions)
- ISO 261 / ISO 724 / ISO 965‑2 (metric threads and tolerances)
- ISO 898‑2, ISO 2320 (mechanical and prevailing torque properties)
- ISO 4759‑1 (product grades and tolerances)
- ISO 8992, ISO 3269, ISO 4042, ISO 10683, ISO 6157‑2

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International
Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 10511 was prepared by Technical Committee ISO/TC 2, Fasteners, Subcommittee SC 12, Fasteners with
metric internal thread.
This third edition cancels and replaces the second edition (ISO 10511:1997), of which it constitutes a minor revision.

Avant-propos
L’ISO (Organisation internationale de normalisation) est une fédération mondiale d’organismes
nationaux de normalisation (comités membres de l’ISO). L’élaboration des Normes internationales est
en général confiée aux comités techniques de l’ISO. Chaque comité membre intéressé par une étude
a le droit de faire partie du comité technique créé à cet effet. Les organisations internationales,
gouvernementales et non gouvernementales, en liaison avec l’ISO participent également aux travaux.
L’ISO collabore étroitement avec la Commission électrotechnique internationale (CEI) en ce qui concerne
la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives
ISO/CEI, Partie 2.
La tâche principale des comités techniques est d’élaborer les Normes internationales. Les projets de
Normes internationales adoptés par les comités techniques sont soumis aux comités membres pour vote.
Leur publication comme Normes internationales requiert l’approbation de 75 % au moins des comités
membres votants.
L’attention est appelée sur le fait que certains des éléments du présent document peuvent faire l’objet de
droits de propriété intellectuelle ou de droits analogues. L’ISO ne saurait être tenue pour responsable de
ne pas avoir identifié de tels droits de propriété et averti de leur existence.
L’ISO 10511 a été élaborée par le comité technique ISO/TC 2, Éléments de fixation, sous-comité SC 12,
Éléments de fixation à filetage métrique intérieur.
Cette deuxième édition annule et remplace la première édition (ISO 10511:1997), qui fait l’objet d’une
révision mineure.
La présente version corrigée de l’ISO 10511:2012 inclut des corrections dans les valeurs du Tableau 1.
