Full title and description

ISO 10509:2012 — Hexagon flange head tapping screws. This International Standard specifies the dimensional, material and acceptance requirements for hexagon flange head tapping screws (sheet‑metal/self‑tapping screws) with nominal thread sizes from ST2,2 up to and including ST9,5, and gives designation and gauging guidance for these fasteners.

Abstract

ISO 10509:2012 defines geometry (head, flange and thread profiles), thread size range (ST2,2 to ST9,5), relevant tolerances and product requirements for hexagon flange head tapping screws, and references related ISO documents for materials, coatings and inspection/acceptance procedures. A normative annex describes gauging of head and flange.

Scope

ISO 10509:2012 applies to hexagon flange head tapping screws intended for use as sheet‑metal/self‑tapping fasteners. The standard covers nominal thread sizes from ST2,2 to ST9,5 inclusive, gives required dimensions for head and flange forms, specifies applicable thread form and tolerances, and points to other ISO standards for material and surface treatment requirements as well as acceptance/inspection procedures. A normative annex describes head and flange gauging methods.

Key topics and requirements

• Thread size range: nominal sizes ST2,2 through ST9,5 and associated dimensional tables and figures.
• Head and flange geometry: dimensions, chamfers/radii and measurement points for hexagon flange head forms and variants.
• References to material and mechanical property standards (e.g., guidance linking to steel and stainless‑steel fastener standards).
• Thread form and tolerances: requirements and references to thread and product‑tolerance standards applicable to tapping screws.
• Surface finishes and coatings: normative references for electroplating, corrosion protection and passivation treatments where applicable.
• Acceptance, inspection and gauging: acceptance procedures and a normative annex describing use of two ring gauges for head/flange verification.
• Designation examples: standard provides recommended designation formats to ensure consistent procurement/specification.

Typical use and users

Manufacturers of tapping screws, fastener distributors, product designers, OEMs, procurement/specification engineers, quality/inspection personnel and standards committees use ISO 10509:2012 to ensure consistent dimensions, interchangeability and inspection criteria for hexagon flange head tapping screws in industrial and consumer applications.

Related standards

ISO 10509:2012 cross‑references and complements other ISO fastener standards such as ISO 2702 (dimensional series for screws), ISO 3506 (stainless steel fastener properties), ISO 898 (mechanical properties of fasteners), ISO 4042 (electroplated coatings), ISO 10683 (zinc flake coatings), ISO 4759 (product tolerances) and ISO 3269 (acceptance inspection for fasteners). These related documents provide material, coating, mechanical property and inspection detail not repeated in ISO 10509.

Q: What does it cover?

A: It covers head and flange geometry, nominal thread sizes ST2,2 to ST9,5, dimensional tolerances, references to applicable material and coating standards, inspection/acceptance guidance and a normative annex on gauging methods.

Q: Who typically uses it?

A: Fastener manufacturers, OEMs, product designers, procurement/specification engineers, distributors and quality/inspection teams use the standard to specify, produce and verify hexagon flange head tapping screws.

Q: Is it current or superseded?

A: ISO 10509:2012 is the second edition (revising ISO 10509:1992). The ISO record shows the 2012 edition as the current published version and notes periodic review/confirmation activity. Users should check ISO or their national standards body for any amendments or later revisions.

Q: Is it part of a series?

A: It is one of the ISO standards covering fasteners and tapping screws; it is normally used alongside other ISO fastener standards (mechanical properties, coatings, tolerances and inspection) to form a complete specification set for screws and bolts.
