DIN 660 is the standard cited for round head solid rivet. This page sets out what the standard controls for this part, reproduces the dimensional table supplied against it, and notes the related designations referenced on drawings.
DIN 660 — Scope
DIN 660 specifies the dimensional requirements for round head solid rivet — gb/t 867 / din 660 (series 097). 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 round head solid rivet — gb/t 867 / din 660 (series 097) 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.
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 |
| 12 | 50 | 24 | 7.5 | 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). 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.
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.
