For turnbuckle, DIN 1480 is the governing document for the dimensions listed below. Mechanical and performance requirements for this part family are set by its own standards, not by the bolt and screw property-class documents.
DIN 1480 — Scope
The table below lists the dimensions catalogued for turnbuckle — iso / din (series 156) under DIN 1480. The scope of DIN 1480 itself is not summarised here — where a figure matters, confirm it against the published document.
Tolerance & Product Grades
Product grade is a concept from dimensional fastener standards and does not apply to DIN 1480. Tolerances for this part are the limits shown against each dimension in the table.
Dimensions Specified by DIN 1480
| Thread size | Total length closed (mm) | Take-up length (mm) | Working load limit (kg) | Material | Reference standard |

Equivalent Standards
Where direct equivalents exist (ISO ↔ DIN, ISO ↔ ASME), they are listed on the parent Turnbuckle — ISO / DIN (Series 156) page.
Always confirm against the dimensions on this page, since some "equivalent" standards differ in tolerances and head geometry.
When to Specify DIN 1480
DIN 1480 is still widely used in European mechanical engineering and as a cross-reference on legacy drawings; its ISO equivalent is preferred for new designs.
Custom manufacturing · Made to drawing
Need a rigging hardware to this standard in a non-standard size?
Parts built to DIN 1480 are already in the catalog, so a special is usually a variation on existing tooling rather than a new design — which is what keeps the cost down. Made by hot forging.
Minimum order from 2,000 pieces; samples within 7 days of drawing approval.
