Overview
ISO 1479:2011 is the International Standard that specifies the characteristics of hexagon head tapping screws with thread sizes from ST 2,2 to ST 9,5 inclusive. Published as the second edition in 2011, it replaces ISO 1479:1983 and was prepared by ISO/TC 2 (Fasteners), Subcommittee SC 13 (Fasteners with non‑metric thread). The standard covers dimensions, types, materials, product grades, tolerances and marking/ designation conventions for these tapping screws.
Key topics and requirements
- Scope: Applies to hexagon head tapping screws with thread sizes ST 2,2 → ST 9,5.
- Dimensions: Head, shank, thread and length dimensions are specified (see Figure 1 and Table 1 in the standard). Types include Type C, Type F, and Type R (rounded end). Preferred lengths and permissible ranges are defined.
- Thread form: Thread specification references ISO 1478 (Tapping screws thread).
- Materials & mechanical properties:
- Steel tapping screws per ISO 2702 (heat‑treated steel tapping screws).
- Corrosion‑resistant stainless steel grades per ISO 3506-4 (e.g., A2-20H, A4-20H, A5-20H).
- Tolerances & product grades: Product grade and dimensional tolerances are referenced to ISO 4759‑1; general fastener requirements to ISO 8992.
- Surface finishes & corrosion protection:
- Electroplated coatings per ISO 4042.
- Non‑electrolytically applied zinc flake coatings per ISO 10683.
- Passivation of stainless steel per ISO 16048.
- Acceptance & inspection: Acceptance inspection procedures are covered by ISO 3269.
- Designation: Standardized designation format (example):
Tapping screw ISO 1479 - ST 3,5 × 16 - A4-20H - R
Applications and users
- Who uses it:
- Fastener manufacturers and suppliers specifying production and catalog data.
- Design and mechanical engineers selecting tapping screws for assemblies.
- Purchasing professionals ensuring compliance and interchangeability.
- Quality and inspection teams performing acceptance testing.
- Practical uses:
- Ensures consistent tapping screw dimensions, thread compatibility and mechanical properties for metal‑to‑metal and sheet metal assemblies.

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 1479 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 1479:1983), which has 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 1479 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 1479:1983), qui a fait l'objet d'une
révision technique.
