ISO 13444:2012 specifies a series of knurling dimensions intended for general use in mechanical engineering and is intended to avoid an unnecessary multiplicity of tools by restricting the profile angle to 90° and by restricting the selection of diametral pitches.

Abstract

Overview

ISO 13444:2012 is an International Standard for Technical Product Documentation (TPD) that defines the dimensioning and indication of knurling on cylindrical workpieces. It standardizes a range of knurling dimensions for general mechanical engineering use to reduce tool multiplicity and improve uniformity and appearance. The standard covers both straight and diamond knurl patterns, prescribes a fixed profile angle, gives allowable diametral pitches, and includes an alternative module-based method in Annex A.

Key topics and requirements

Knurling types:
- Type A - straight knurling
- Type B - diamond knurling (teeth either parallel to the axis or at a 30° helix)
Profile angle: fixed at 90° for the standardized method.
Diametral pitch (p): selectable from a restricted list to limit tool variety - 0.4, 0.5, 0.6, 0.8, 1.0, 1.2, 1.6 mm.
Diameter relations: finished and pre-knurl diameters are related by pitch-dependent offsets:
- Type A: diameter change ≈ ±0.5·p
- Type B: diameter change ≈ ±0.67·p
Chamfer/radius: recommended chamfer c = p when knurl width b ≥ 6 mm; for b
