Overview

ISO 15481:1999 is an international standard published by the International Organization for Standardization (ISO) that specifies the characteristics of cross recessed pan head drilling screws with tapping screw thread designed for sheet metal applications. This standard defines essential parameters such as dimensions, thread types, head design, and mechanical properties for self-drilling screws with pan heads featuring cruciform recesses. These screws incorporate a tapping screw thread, making them suitable for drilling and fastening in thin metal sheets without pre-drilling holes.

The standard was developed by ISO Technical Committee ISO/TC 2 on Fasteners and is applicable to screws with thread sizes ranging from ST2.9 to ST6.3. ISO 15481 helps ensure consistent quality, compatibility, and performance for fastening components used in manufacturing and construction industries worldwide.

Key Topics

• Screw Type: Cross recessed pan head with a wide cylindrical dome shape suitable for self-drilling.
• Threading: Tapping screw thread specifically designed for sheet metal fastening (sizes ST2.9 to ST6.3).
• Dimensions and Tolerances: Detailed dimensional specifications including thread pitch, head dimensions, and recess depth; critical for ensuring interchangeability and proper fitting.
• Drive Types: Specifies two types of cruciform recesses (Type H and Type Z) that influence torque application and driver compatibility.
• Material and Mechanical Properties: References ISO 10666 for mechanical and functional requirements, ensuring optimal strength and durability.
• Surface Finishing: Guidelines for electroplating and other treatments as per ISO 4042 to enhance corrosion resistance.
• Quality Control: Includes acceptance inspection criteria based on ISO 3269 to maintain consistent manufacturing standards.

Applications

ISO 15481 screws are primarily used in applications requiring secure fastening in thin metal sheets where self-drilling capabilities reduce assembly time and eliminate the need for pre-drilled holes. Typical use cases include:

• Building and Construction: Securing roofing sheets, wall cladding, HVAC panels, and metal frameworks.
• Automotive and Transportation: Fastening interior and exterior vehicle panels, mounting brackets, and assemblies where sheet metal components are common.
• Electrical Equipment: Securing enclosures, equipment boxes, and components manufactured from sheet metal.
• Industrial Manufacturing: Assembly of appliances, machinery, and fabricated metal products that require reliable self-drilling fasteners.

By complying with ISO 15481, manufacturers and users ensure their screws meet stringent performance and quality benchmarks, leading to more reliable joints, reduced installation time, and improved overall safety.

Related Standards

To fully apply and understand ISO 15481, several related ISO standards are referenced and important for comprehensive implementation:

• ISO 10666: Covers mechanical and functional properties of self-drilling screws.
• ISO 1478: Details the threading specifications for sheet metal screws.
• ISO 4757: Defines characteristics of cruciform recesses for fastening screws.
• ISO 4759-1: Specifies tolerances for fasteners including screws, studs, and nuts.
• ISO 4042: Addresses electrolytic coatings for fasteners to improve corrosion resistance.
• ISO 3269: Establishes acceptance inspection procedures for fasteners.

These interconnected standards ensure that screws manufactured and used under ISO 15481 are fully compliant with industry requirements for mechanical strength, dimensional accuracy, corrosion protection, and quality assurance.

---

ISO 15481:1999 is a vital reference for engineers, manufacturers, and quality managers involved in the design, production, and use of self-drilling pan head screws with tapping threads, especially in sheet metal fabrication. Utilizing this standard supports efficient assembly processes, consistent product quality, and enhanced fastening reliability in various industrial sectors.

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 3.
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.
International Standard ISO 15481 was prepared by Technical Committee ISO/TC 2, .

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 3.
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.
La Norme internationale ISO 15481 a été élaborée par le comité technique ISO/TC 2, Éléments de fixation.
