Full title and description

ISO 14279:2002 — Aerospace — Drives, internal, cruciform — Metric series. This International Standard specifies the dimensions of metric internal cruciform drives used on metric screws for aerospace applications, defining sizes for the metric series of internal cruciform drive forms and their intended nominal thread diameter range.

Abstract

ISO 14279:2002 specifies dimensional requirements for internal cruciform (cross‑shaped) drives used in metric screws, covering the metric series drive sizes intended for nominal thread diameters from 1.6 mm up to 20 mm. The standard provides geometry and size limits to ensure interchangeability and correct fit of internal cruciform drives in aerospace fasteners.

Scope

The standard applies to metric internal cruciform drives used on metric screws in the nominal thread diameter range 1.6 mm to 20 mm. It defines the form, basic dimensions and tolerances necessary to ensure correct engagement and interchangeability of internal cruciform drives in aerospace fasteners and related components.

Key topics and requirements

• Definition of metric internal cruciform drive forms and series (geometric profiles and dimensions).
• Size designations and correspondence to nominal thread diameters (covering nominal diameters 1.6 mm to 20 mm).
• Dimensional limits and tolerances necessary for manufacturing and inspection to assure fit and function.
• Requirements aimed at interchangeability and secure drive engagement for aerospace fasteners.
• Cross‑references to related drive standards for ribbed/unribbed or alternate drive types used in aerospace applications.

Summary based on the published ISO record and related national/adoption records.

Typical use and users

Primary users include aerospace OEM design and fastener engineering teams, fastener and screw manufacturers, quality and inspection departments, procurement teams specifying aerospace fasteners, and standards committees. The standard is used when defining internal cruciform drive sizes for aerospace screw families and for ensuring interchangeability across suppliers.

Related standards

National adoption: BS ISO 14279:2002 (identical adoption). Related ISO items include standards addressing ribbed or alternate internal cruciform drives (for example ISO 14280 and other aerospace fastener/drive standards). Users should check the ISO catalogue or national standards body for linked or superseding documents before specifying.
