DIN 660 is the governing dimensional standard for round head solid rivet. 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.
DIN 660 — Scope
DIN 660 specifies the dimensions and tolerances of round head solid rivet — gb/t 867 / din 660 (series 097). 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
DIN 660, alongside the related GB/T 867 / DIN 660 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.
Dimensions Specified by DIN 660
| Nominal diameter (mm) | Length L (mm) | Head diameter dk (mm) | Head height k (mm) | Material | Reference standard |

Equivalent Standards
Where direct equivalents exist (ISO ↔ DIN, ISO ↔ ASME), they are listed on the parent Round Head Solid Rivet — GB/T 867 / DIN 660 (Series 097) page. Always confirm against the dimensions on this page, since some "equivalent" standards differ in tolerances and head geometry.
When to Specify DIN 660
DIN 660 is still widely used in European mechanical engineering and as a cross-reference on legacy drawings; its ISO equivalent is preferred for new designs.
