Overview

ISO 1207:2011 is an international standard published by the International Organization for Standardization (ISO) that specifies the characteristics of slotted cheese head screws of product grade A. These screws come with metric threads ranging from M1.6 up to M10 inclusive. As a third edition update, this 2011 standard replaces the previous ISO 1207:1992 and introduces technical revisions to enhance consistency, quality, and compatibility in fastener production and application worldwide.

This standard ensures uniformity in dimensions, materials, mechanical properties, and tolerances for slotted cheese head screws, which are widely used in mechanical assemblies and precision engineering. It harmonizes specifications with other relevant ISO standards related to threads, mechanical properties, coatings, and acceptance inspection, thereby facilitating global trade and interoperability.

Key Topics

• Scope and Application
  Specifies product grade A slotted cheese head screws with thread sizes from M1.6 to M10, suitable for various mechanical fastening purposes.

• Dimensions and Tolerances
  Defines precise dimensions including head heights, diameters, slot widths, and thread pitches following ISO 225. Tolerances are in accordance with ISO 4759-1, ensuring interchangeability and reliable assembly.

• Material and Mechanical Properties
  Covers screws made from steel, stainless steel, and non-ferrous metals. Mechanical properties align with ISO 898-1 (carbon and alloy steel), ISO 3506-1 (corrosion-resistant stainless steel), and ISO 8839 (non-ferrous metals), providing clear classification by property class (e.g., 4.8, 5.8, A2-50).

• Surface Finishes and Coatings
  Addresses requirements for electroplated coatings (ISO 4042), passivation of stainless steel (ISO 16048), and non-electrolytically applied zinc flake coatings (ISO 10683). This section supports corrosion resistance and application-specific durability.

• Inspection and Quality Assurance
  Acceptance inspection criteria are guided by ISO 3269. Surface discontinuities limits follow ISO 6157-1. These ensure product compliance and reliability in service.

• Designation System
  Standardized naming convention for the screws includes thread size, nominal length, and property class for clear identification, e.g., "Cheese head screw ISO 1207 - M5 × 20 - 4.8".

Applications

Slotted cheese head screws standardized under ISO 1207:2011 are extensively used in applications requiring:

• Precision Fastening
  Ideal for mechanical, electronic, and electrical equipment assemblies where accurate fit and consistent performance are critical.

• General Construction and Manufacturing
  Common in machines, automotive components, instruments, and equipment requiring fasteners with reliable thread engagement and load capacity.

• Corrosion-Resistant Assemblies
  Stainless steel versions are suitable for outdoor, marine, and chemical environments due to specified coatings and passivation treatments.

• Maintenance and Repair
  Enables standardization in replacement parts, reducing downtime and ensuring compatibility with existing assemblies.

Related Standards

ISO 1207:2011 references and aligns with several key ISO standards to ensure full integration within the fastener ecosystem:

• ISO 225 - Symbols and descriptions of fastener dimensions
• ISO 261, ISO 965-2, ISO 965-3 - Metric screw thread dimensions and tolerances
• ISO 898-1 - Mechanical properties of carbon and alloy steel fasteners
• ISO 3506-1 - Mechanical properties of stainless steel fasteners
• ISO 4042 - Electroplated coatings for fasteners
• ISO 10683 - Non-electrolytically applied zinc flake coatings
• ISO 3269 - Acceptance inspection for fasteners
• ISO 4759-1 - Tolerances for fasteners of product grades A, B, and C
• ISO 6157-1 - Surface discontinuities limits

Utilizing these harmonized standards ensures that slotted cheese head screws comply with both dimensional and performance criteria expected in modern engineering practices.

---

ISO 1207:2011 provides manufacturers, designers, and quality professionals with a comprehensive framework for producing and specifying slotted cheese head screws of product grade A. This standard supports interoperability, quality assurance, and global trade by defining exact parameters for fastener characteristics, materials, finishes, and inspection.

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 1207 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 1207:1992), which has been technically
revised.
INTERNATIONAL STANDARD ISO 1207:2011(E)

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'ISO 1207 a été élaborée par le comité technique ISO/TC 2, Éléments de fixation, sous-comité SC 11,
Éléments de fixation à filetage métrique extérieur.
Cette troisième édition annule et remplace la deuxième édition (ISO 1207:1992), qui a fait l'objet d'une
révision technique.
