Overview

EN ISO 15065:2005 (ISO 15065:2005) specifies the dimensions and designation of countersinks intended for use with countersunk head screws whose head configuration conforms to ISO 7721. Adopted by CEN and published in 2005, the standard ensures consistent countersink geometry for a wide range of screw types, enabling correct seating, repeatable assembly and clear representation in technical drawings.

Key topics and requirements

  • Scope and applicability: Covers countersinks for many common screw types (slotted, cross‑recessed, hexalobular, tapping and drilling screws) referenced by standards such as ISO 2009, 2010, 7046‑1/2, 7047, 7050/51, 14584/86/87, 15482 and 15483.
  • Countersink dimensions: Specifies the geometric dimensions of countersinks (as shown in the standard’s figure and tabulated in Table 1) for nominal thread sizes (metric and tapping thread designations). Dimensioning enables correct head seating and clearance.
  • Clearance hole reference: Where applicable, clearance hole sizing is referenced to ISO 273 (medium series, tolerance H13) to ensure proper fit between screw shank and hole.
  • Designation and marking: Defines how to designate a countersink unambiguously (example: “Countersink ISO 15065 - 4” for nominal size 4).
  • Representation in drawings: Provides the standard symbol and drawing representation for countersinks so technical drawings are clear and unambiguous.
  • Normative references: Lists indispensable related standards that must be used together with EN ISO 15065 for complete specification.

Applications and users

This standard is practical for:

  • Mechanical design engineers and CAD drafters who need correct countersink geometry and drawing symbols for assemblies.
  • Fastener and tooling manufacturers producing countersink cutters, jigs or reamers matched to screw head geometry.
  • CNC machinists and production engineers programming hole and countersink operations for consistent part quality.
  • Quality inspectors and procurement specialists who verify countersink dimensions, tolerance and conformity.
  • Suppliers and assemblers focused on interchangeability, secure seating of countersunk screws, and preventing head deformation or misalignment.

Using EN ISO 15065 improves assembly reliability, reduces rework, and supports international interoperability of threaded fasteners and mating components.
