Specification summary of DIN 580 as applied to lifting eye bolt: the dimensions the standard fixes, the full size range supplied, and the related designations commonly cross-referenced.
DIN 580 — Scope
DIN 580 specifies the dimensional requirements for lifting eye bolt — gb/t 825 / din 580 (series 036). Material, surface condition and any performance rating are set by separate documents specific to this part family — ISO 898-1 and ISO 898-2, which govern bolt and nut property classes, do not apply here.
Tolerance & Product Grades
Tolerances for lifting eye bolt — gb/t 825 / din 580 (series 036) are given as limits on the individual dimensions in the table rather than as a fastener product grade. Where a general-tolerance class is cited on the drawing instead, it applies to the dimensions not otherwise toleranced.

Equivalent Standards
Where direct equivalents exist (ISO ↔ DIN, ISO ↔ ASME), they are listed on the parent Lifting Eye Bolt — GB/T 825 / DIN 580 (Series 036) page. Always confirm against the dimensions on this page, since some "equivalent" standards differ in tolerances and head geometry.
Companion Standards
DIN 580 controls only the geometry of lifting eye bolt — gb/t 825 / din 580 (series 036). Surface finish is governed by separate finish standards (for example ISO 4042 for electroplating), and corrosion testing by ISO 9227 (neutral salt spray). Mechanical performance is set by the standards specific to this part family, not by ISO 898-1 or ISO 898-2, which apply to bolts, screws and nuts.
