Full title and description
Technical product documentation (TPD) — Dimensioning and indication of knurling (ISO 13444:2012). This International Standard specifies a series of knurling dimensions and rules for indicating knurled features on technical drawings to promote consistency and to avoid an unnecessary multiplicity of tools.
Abstract
ISO 13444:2012 defines standard knurling dimensions intended for general use in mechanical engineering and restricts the knurl profile angle to 90° and the selection of diametral pitches so as to simplify tooling choices and drawing indications.

Scope
This standard specifies a set of standard knurling dimensions and the conventions for indicating knurled features on engineering drawings. It is intended for general mechanical engineering use and aims to reduce unnecessary variety in knurl tooling by standardising profile angle (90°) and permitted diametral pitches. The standard covers dimensioning and graphical/textual indication practices rather than manufacturing process parameters.
Key topics and requirements
- Standardised knurl profile angle (restricted to 90°) for drawing indication.
- Restricted selection of diametral pitches to limit tooling multiplicity.
- Conventions for dimensioning knurled features on 2D engineering drawings (symbol placement, dimension lines, and notes).
- Guidance intended for use with wider TPD (technical product documentation) practices and complementary ISO drawing standards.
Typical use and users
Used by mechanical designers, draughtspeople, CAD engineers, technical authors, and manufacturing engineers to ensure consistent specification of knurled surfaces on parts (shafts, knobs, handles, fastener heads, etc.). Also consulted by standards committees and quality engineers when preparing drawings or checking supplier documentation.
Related standards
ISO 13444:2012 is part of the ISO Technical Product Documentation family and is commonly used alongside other TPD/GPS documents such as ISO 129 (presentation and indication of dimensions and tolerances), ISO 1101 (geometrical tolerancing), ISO 16792 (digital product definition/CAD practices) and ISO 5457 (drawing sheet sizes and layout). These related standards provide complementary rules for dimensioning, tolerancing, CAD annotation and drawing formats.

FAQ
Q: What is this standard?
A: ISO 13444:2012 is an ISO International Standard titled "Technical product documentation (TPD) — Dimensioning and indication of knurling" that sets out standard dimensions and drawing indications for knurled features.
Q: What does it cover?
A: It covers standard knurl dimensions, limits the knurl profile angle to 90°, restricts the selection of diametral pitches, and provides conventions for showing knurled features on technical drawings; it does not prescribe manufacturing processes.
Q: Who typically uses it?
A: Mechanical designers, draughting/CAD engineers, technical documentation authors, manufacturing and quality engineers, and standards professionals use it when specifying or interpreting knurled features on parts and drawings.
Q: Is it current or superseded?
A: The 2012 edition (Edition 1) is published and was confirmed in ISO periodic review, so it remains the current edition as recorded by ISO. Users should verify any later amendments or revisions via their national standards body or ISO catalogue before quoting the standard in new specifications.
Q: Is it part of a series?
A: ISO 13444 is part of the broader Technical Product Documentation (TPD) family of ISO standards (the ISO 129 series, ISO 1101, ISO 16792, ISO 5457, etc.) which collectively cover drawing presentation, dimensioning, tolerancing and digital product definition practices.
Q: What are the key keywords?
A: Key keywords include knurling, knurl, diametral pitch, profile angle, technical product documentation, dimensioning, drawing indication, TPD.
