Overview

ISO 14587:2011 is an International Standard developed by the International Organization for Standardization (ISO) that specifies the characteristics of hexalobular socket raised countersunk (oval) head tapping screws. Covering thread sizes from ST2.9 up to ST6.3, this standard ensures uniformity and quality in the production and application of these specialized fasteners. It replaces the previous edition ISO 14587:2001 with minor revisions to maintain up-to-date technical requirements.

This standard is crucial for manufacturers, engineers, and quality inspectors involved in the design, production, and utilization of tapping screws that require high precision and reliability. It defines dimensional requirements, mechanical properties, tolerances, and finish options to guarantee compatibility and performance in industrial applications.

Key Topics

• Thread Sizes and Dimensions
  ISO 14587:2011 specifies tapping screws with thread sizes ST2.9 to ST6.3. Detailed dimensional data, such as nominal lengths, head heights, and socket dimensions, are provided to standardize products. These measurements align with ISO 225, which defines symbols and dimensions for fasteners.

• Head Types
  The screws feature hexalobular socket raised countersunk (oval) heads with edge options including rounded or flat. Three head types are included: Type C, Type F, and Type R (round end), allowing design flexibility.

• Material and Mechanical Properties
  Steel materials complying with ISO 2702 are mandated, ensuring high mechanical strength and heat treatment standards for mechanical properties. Product grade A quality is specified for this category of fasteners.

• Tolerances and Acceptance
  Tolerances for dimensions and thread quality follow ISO 4759-1, while acceptance inspection procedures adhere to ISO 3269 to guarantee compliance with standards before deployment.

• Driving Feature
  The hexalobular internal driving feature is specified in ISO 10664, ensuring consistent engagement with hexalobular socket tools for secure fastening.

• Surface Finishing and Coatings
  Electroplated coatings must meet ISO 4042 requirements, while non-electrolytically applied zinc flake coatings conform to ISO 10683. Custom finishes or coatings can be agreed upon between supplier and purchaser.

• Cross-Referenced Standards
  The standard references related ISO documents to cover all relevant aspects of tapping screw manufacture and inspection comprehensively.

Applications

Hexalobular socket raised countersunk (oval) head tapping screws standardized by ISO 14587:2011 have broad application in industries requiring secure and precise fastening solutions, such as:

• Automotive Manufacturing
  Ensuring reliable assembly of components where high torque and vibration resistance are critical.

• Electronics and Electrical Equipment
  Providing secure fastening with minimal risk of damage due to the countersunk head design and standardized socket.

• Machinery and Equipment
  Used in precision machinery where exact dimensions and mechanical fitness are essential for performance.

• Aerospace and Defense
  Enabling consistent, high-strength fastening compliant with stringent quality control standards.

• General Industrial Assembly
  Widely employed in construction, metalworking, and maintenance sectors requiring robust tapping screws.

Using these standardized screws allows manufacturers and users to optimize assembly line efficiency, improve product reliability, and maintain global compatibility in supply chains.

Related Standards

ISO 14587:2011 should be used in conjunction with the following related International Standards to ensure comprehensive specification and quality:

• ISO 225 – Defines fastener dimension symbols and descriptions
• ISO 1478 – Specifies tapping screw threads
• ISO 2702 – Covers mechanical properties and heat treatment of steel tapping screws
• ISO 3269 – Details acceptance inspection procedures for fasteners
• ISO 4042 – Requirements for electroplated coatings on fasteners
• ISO 4759-1 – Provides tolerances for bolts, screws, studs, and nuts
• ISO 7721 – Covers countersunk head screw dimensions and gauging
• ISO 10664 – Specifies hexalobular internal driving features on screws and bolts
• ISO 10683 – Rules for non-electrolytically applied zinc flake coatings on fasteners

Adhering to these complementary standards ensures that tapping screws conform to rigorous industry requirements covering dimensions, materials, coatings, and mechanical performance.

---

By following ISO 14587:2011, industry professionals can confidently select, manufacture, and inspect hexalobular socket raised countersunk (oval) head tapping screws that meet international quality and performance benchmarks for a wide range of technical and industrial 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 14587 was prepared by Technical Committee ISO/TC 2, Fasteners, Subcommittee SC 10, Product
standards for fasteners.
This second edition cancels and replaces the first edition (ISO 14587:2001), 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
