Overview

ISO 10509:2012 is the International Standard that specifies hexagon flange head tapping screws. The standard covers thread sizes from ST2,2 up to and including ST9,5, and provides the dimensional, material and acceptance framework required for consistent manufacture, inspection and designation.

Key elements in the standard include references to drawings and tables (Figure 1 and Table 1) for dimensions, normative references to related ISO documents for materials and coatings, and a normative annex for head and flange gauging.

Key Topics

• Scope and sizes: Thread sizes ST2,2 through ST9,5 are covered; dimensional details are provided in Figure 1 and Table 1.
• Types and form: The document includes head/end types (for example Type C, Type F and Type R) and specifies where dimensions such as chamfer/radius and flange details are to be measured.
• Materials and mechanical properties: Steel tapping screws are referenced to ISO 2702; corrosion‑resistant stainless steel tapping screws reference ISO 3506-4.
• Thread and tolerances: Thread form and requirements refer to ISO 1478; product tolerances follow ISO 4759-1 (product grade A referenced in the document).
• Surface finishes and coatings: Electroplating requirements reference ISO 4042; non-electrolytically applied zinc flake coatings reference ISO 10683; passivation for stainless steel references ISO 16048.
• Acceptance and inspection: Acceptance procedure is specified in ISO 3269; general fastener requirements reference ISO 8992.
• Designation examples: The standard gives clear designation formats (example: "Tapping screw ISO 10509 - ST3,5 × 16 - St - R"), making procurement and specification consistent.
• Gauging (Annex A): A normative check describes the use of two ring gauges (A and B) to verify head and flange dimensions; Gauge A seats on the flange while Gauge B is placed on the top of the head and the two must not contact.

Applications

• Specification and procurement of tapping screws for manufacturing and assembly operations.
• Quality control and acceptance testing in fastener production and incoming inspection at assembly plants.
• Engineering design where interchangeability and conformity to international fastener norms are required.
• Coating and corrosion‑resistance decisions, using the referenced ISO documents to select suitable finishes.

Related Standards

By aligning design, procurement and inspection with ISO 10509:2012 and its referenced standards, organisations ensure consistent dimensions, clear designation, and reliable acceptance criteria for hexagon flange head tapping screws.

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 10509 was prepared by Technical Committee ISO/TC 2, Fasteners, Subcommittee SC 13, Fasteners with
non-metric thread.
This second edition cancels and replaces the first edition (ISO 10509:1992), which has been technically revised.
In particular, Clauses 2 and 5, Tables 1 and 2, as well as Figures 1 and A.1 have been technically revised.

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 10509 a été élaborée par le comité technique ISO/TC 2, Éléments de fixation, sous-comité SC 13,
Éléments de fixation à filetage non métrique.
Cette deuxième édition annule et remplace la première édition (ISO 10509:1992), qui a fait l’objet d’une révision
technique. En particulier, les Articles 2 et 5, les Tableaux 1 et 2, ainsi que les Figures 1 et A.1 ont fait l’objet
d’une révision technique.
