Full title and description

ISO 1207:2011 — Slotted cheese head screws — Product grade A. This International Standard specifies the characteristics and designation of slotted (slotted cheese head) machine screws of product grade A with metric thread sizes from M1,6 to M10 inclusive; it replaces ISO 1207:1992.

Abstract

ISO 1207:2011 defines dimensions, head and slot geometry, nominal lengths and designation conventions for slotted cheese head screws (product grade A), and references related fastener standards for threads, mechanical properties and tolerances.

Scope

This standard applies to slotted cheese head screws manufactured to product grade A with metric threads from M1,6 up to and including M10. It specifies head diameters and heights, slot dimensions, nominal lengths, designation format and references for thread and mechanical-property requirements; where special requirements are needed they are to be taken from related ISO standards (for example ISO 261, ISO 225, ISO 965-2, ISO 898-1, ISO 3506-1, ISO 4759-1).

Key topics and requirements

• Thread size range: metric threads M1.6 to M10 (inclusive).
• Head geometry and dimensions for slotted cheese head screws (diameter, height, slot width and depth).
• Nominal lengths and designation conventions for clear identification of screw type and size.
• Tolerances and acceptance criteria referenced to ISO tolerance and fastener standards (e.g., ISO 4759-1 for dimensional tolerances and ISO 3269 for acceptance markings).
• Material and mechanical property linkage: carbon/alloy steel and stainless steel property classes referenced to ISO 898-1 and ISO 3506-1.
• Surface finishes and corrosion-protection references (electroplating, passivation and zinc‑flake coatings referenced in related ISO documents).
• Intended interchangeability and compatibility with other metric fastener standards (thread, fit and designation standards).

Typical use and users

Users include fastener manufacturers, mechanical and product designers, procurement and quality assurance teams, testing laboratories and standards committees. Typical applications are general machine construction, equipment assembly and repair where slotted cheese head screws of specified dimensions and interchangeability are required.

Related standards

Commonly referenced and complementary standards include: ISO 261 (general metric series of preferred numbers and sizes), ISO 225 (symbols and dimension descriptions for fasteners), ISO 965-2 (tolerance for metric threads), ISO 898-1 (mechanical properties of fasteners made of carbon and alloy steel), ISO 3506-1 (mechanical properties of corrosion‑resistant stainless‑steel fasteners), ISO 4759-1 (tolerances for fasteners), ISO 10683 and ISO 16048 (coatings/passivation), and ISO 3269 (acceptance inspection and marking).

FAQ

Q: What is this standard?

A: ISO 1207:2011 is an International Standard specifying the dimensions, head/slot geometry and designation for slotted cheese head screws of product grade A with metric threads from M1,6 to M10.

Q: What does it cover?

A: It covers dimensional requirements (head and slot), nominal lengths, designation rules and pointers to related standards for thread tolerances, mechanical properties and coatings; it does not replace the need to consult material- and coating-specific standards for mechanical or corrosion performance.

Q: Who typically uses it?

A: Manufacturers of screws and fasteners, design engineers, purchasing/procurement, quality control and testing labs use ISO 1207 when specifying or verifying slotted cheese head screws for assemblies and supply contracts.

Q: Is it current or superseded?

A: ISO 1207:2011 superseded ISO 1207:1992. The 2011 edition remains the current published edition and was reviewed/confirmed by ISO during the periodic review cycle (confirmed in 2021).

Q: Is it part of a series?

A: It is part of the family of ISO fastener standards and is cross-referenced with other ISO standards governing threads, dimensions, tolerances and mechanical properties (see Related standards above).

Q: What are the key keywords?

A: Slotted cheese head, product grade A, metric fasteners, M1.6–M10, screw dimensions, ISO 1207.
