Overview
ISO 7045:2011 is an international standard published by the International Organization for Standardization (ISO), specifying the characteristics of pan head screws with type H or type Z cross recess. Targeted at product grade A screws, the standard covers sizes with threads ranging from M1.6 to M10 inclusive. This third edition, issued in 2011, updates the prior 1994 edition with minor revisions. ISO 7045:2011 defines the dimensional, mechanical, and material requirements, ensuring quality and interchangeability for pan head screws used in a broad spectrum of industrial and manufacturing applications.
Key Topics
- Scope & Dimensions: Specifies pan head screws with type H or Z cross recesses, incorporating thread sizes between M1.6 and M10. Detailed measurements such as head height, diameter, recess depth, and thread pitch are defined to ensure precision.
- Material & Mechanical Properties: Covers steel, stainless steel, and non-ferrous metals complying with related ISO standards (ISO 898-1, ISO 3506-1, ISO 8839). Property classes such as 4.8 and stainless steel grades A2-50, A2-70 are referenced.
- Cross Recess Types: Defines type H and type Z cross recesses based on ISO 4757 ensuring compatibility with relevant screwdrivers and assembly tools.
- Tolerances & Quality Grades: Includes tolerance classes, surface integrity limits, and product grades according to ISO 4759-1 and ISO 6157-1 for surface discontinuities.
- Finish & Coatings: Details requirements for electroplating (ISO 4042), zinc flake coatings (ISO 10683), and passivation treatments for stainless steel (ISO 16048) to enhance corrosion resistance and durability.
- Designation Format: Provides a clear example of how to designate pan head screws under the standard including thread size, length, property class, and cross recess type, for instance:
Pan head screw ISO 7045 - M5 × 20 - 4.8 - Z
Applications
Pan head screws compliant with ISO 7045:2011 are widely used in industries requiring reliable fastening solutions with high precision and standardized dimensions. Typical applications include:
- Electronics & Electrical Assemblies: Small diameter screws with precise cross recesses allow secure assembly of consumer electronics, appliances, and instrumentation.
- Automotive & Machinery Manufacturing: Ensures parts are fastened consistently with high mechanical strength property classes, critical for safety and structural integrity.
- Construction & Metal Fabrication: Pan head screws facilitate fastening components where heads need to sit flush or slightly above the surface.
- Medical Devices: Stainless steel variants provide corrosion resistance and mechanical reliability essential for medical instrumentation.
- General Industrial Usage: Versatile compatibility with common screwdriver types and standardized thread pitch simplifies maintenance and assembly processes.
Related Standards
ISO 7045:2011 references and aligns with several key international standards to maintain consistency in thread specifications, mechanical properties, and testing:
- ISO 261 - General plan for metric screw threads
- ISO 898-1 - Mechanical properties of carbon and alloy steel fasteners
- ISO 965-2 - Tolerances for general purpose metric screw threads
- ISO 3506-1 - Mechanical properties of stainless steel fasteners
- ISO 4757 - Cross recess details for screws
- ISO 4759-1 - Tolerances for product grades of fasteners
- ISO 4042 - Electroplated coating requirements
- ISO 6157-1 - Surface discontinuity limits for bolts and screws
- ISO 10683 - Zinc flake coating standards
- ISO 16048 - Passivation of corrosion-resistant stainless steel fasteners
These complementary standards provide comprehensive guidance for material selection, thread tolerances, surface finishes, and quality assurance, reinforcing the reliability of pan head screws manufactured under ISO 7045:2011.
By adhering to ISO 7045:2011, manufacturers and users of pan head screws can ensure consistent quality, dimensional accuracy, and compatibility across global supply chains, facilitating effective and reliable assembly in diverse technical fields.

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 7045 was prepared by Technical Committee ISO/TC 2, Fasteners, Subcommittee SC 11, Fasteners with
metric external thread.
This third edition cancels and replaces the second edition (ISO 7045:1994), 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.
