Overview

SIST ISO 10509:2015 is an international standard published by the Slovenian Institute for Standardization (SIST), mirroring ISO 10509:2012. The standard specifies requirements for hexagon flange head tapping screws with thread sizes from ST2.2 up to ST9.5. These fasteners are widely used for creating secure threaded joints in materials like sheet metal, especially in automotive, construction, appliance, and machinery manufacturing.

The standard covers important aspects such as dimensions, material properties, mechanical requirements, tolerances, and finish/coating options. Adhering to SIST ISO 10509:2015 ensures compatibility and reliability in fastener performance, supporting quality assurance, safety, and interoperability across industries.

Key Topics

• Scope: Defines hexagon flange head tapping screws with thread sizes ranging from ST2.2 to ST9.5.
• Dimensions: Specifies key dimensions and tolerances for different screw types and sizes to guarantee interchangeability and fit.
• Thread Types: Includes compatibility with relevant thread standards for tapping screws.
• Materials: Covers requirements for both steel and corrosion-resistant stainless steel tapping screws.
• Mechanical Properties: References international demands for strength, hardness, and durability.
• Finishes and Coatings: Allows for various finishes including electroplated, non-electrolytic zinc flake, and passivation for corrosion resistance.
• Inspection and Acceptance: Outlines acceptance inspection procedures to verify compliance.
• Designation: Provides guidelines for unambiguous product identification and ordering, including thread size, length, material, and end type.

Applications

Hexagon flange head tapping screws are essential components in several sectors leveraging their self-tapping and secure fastening features:

• Automotive Manufacturing: Used to assemble body panels, brackets, and engine components, offering vibration-resistant joints.
• Appliance Industry: Preferred in assembling household appliances, HVAC equipment, and electronic enclosures.
• Construction and Infrastructure: Suitable for fastening steel frames, panels, and substructures where secure and reliable connections are required.
• Machinery and Equipment: Applied in the assembly of machinery covers, guards, and structural components.
• General Engineering: Employed wherever reliable, standardized tapping screws are needed for safety and performance.

By following SIST ISO 10509:2015, manufacturers and end-users benefit from streamlined procurement, better quality assurance, improved safety, and easier maintenance thanks to standardized fastener interfaces.

Related Standards

Several other international standards are referenced and support effective application of SIST ISO 10509:2015:

• ISO 1478: Tapping screws thread.
• ISO 2702: Heat-treated steel tapping screws - Mechanical properties.
• ISO 3506-4: Mechanical properties of corrosion-resistant stainless steel fasteners.
• ISO 4759-1: Tolerances for fasteners - Product grades A, B, and C.
• ISO 4042: Electroplated coatings for fasteners.
• ISO 10683: Non-electrolytically applied zinc flake coatings.
• ISO 16048: Passivation of corrosion-resistant stainless-steel fasteners.
• ISO 3269: Fastener acceptance inspection.
• ISO 225 and ISO 8992: Provide symbols, dimension definitions, and general fastener requirements.

By referencing these standards, SIST ISO 10509:2015 ensures comprehensive quality and compatibility for international fastener applications.

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.
