T 6170 is the governing dimensional standard for wire rope. This page sets out the scope of the standard, reproduces the full size table it specifies, and lists the DIN/ISO/ASME cross-references commonly cited in datasheets and drawings.
T 6170 — Scope
T 6170 specifies the dimensions and tolerances of wire rope — gb/t 6170 / iso 4032 (series 063). Material, property class, surface finish and packaging are governed by separate documents in the same standards family (for example ISO 898-1 for the mechanical property classes of bolts and screws).
Tolerance & Product Grades
T 6170, alongside the related GB/T 6170 / ISO 4032 entries on this site, specifies product grades (typically A or B for fine work and C for general engineering) and tolerance classes for the controlling dimensions. Choose the grade against the precision your application requires.

Equivalent Standards
Where direct equivalents exist (ISO ↔ DIN, ISO ↔ ASME), they are listed on the parent Wire Rope — GB/T 6170 / ISO 4032 (Series 063) page. Always confirm against the dimensions on this page, since some "equivalent" standards differ in tolerances and head geometry.
When to Specify T 6170
Choose T 6170 for international engineering work and OEM supply where ISO standards are the contractual reference. It is the default modern specification for wire rope — gb/t 6170 / iso 4032 (series 063).
