DIN 660 is the international standard for round head solid rivet — gb/t 867 / din 660 (series 097). This page sets out what the standard governs, the size range it specifies, and the related standards you will see referenced in datasheets.
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 |
|---|---|---|---|---|---|
| 2.5 | 8 | 5 | 1.6 | Aluminum | GB/T 867 / DIN 660 |
| 3 | 10 | 6 | 1.9 | Aluminum | GB/T 867 / DIN 660 |
| 4 | 16 | 8 | 2.5 | Carbon steel | GB/T 867 / DIN 660 |
| 5 | 20 | 10 | 3.1 | Carbon steel | GB/T 867 / DIN 660 |
| 6 | 25 | 12 | 3.8 | Carbon steel | GB/T 867 / DIN 660 |
| 8 | 32 | 16 | 5.0 | Carbon steel | GB/T 867 / DIN 660 |
| 10 | 40 | 20 | 6.3 | Carbon steel | GB/T 867 / DIN 660 |

Companion Standards
DIN 660 controls only the geometry of round head solid rivet — gb/t 867 / din 660 (series 097). The mechanical strength is set by ISO 898-1 (bolts and screws) or ISO 898-2 (nuts); the surface finish is governed by separate finish standards (e.g. ISO 4042 for electroplating). For corrosion testing, the relevant document is ISO 9227 (neutral salt spray).
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.
