DIN 1473 is the standard cited for grooved pins (din 1471–1474). 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 1473 — Scope
The table below lists the dimensions catalogued for grooved pins (din 1471–1474) under DIN 1473. The scope of DIN 1473 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 1473. Tolerances for this part are the limits shown against each dimension in the table.
Dimensions Specified by DIN 1473
| Nominal diameter d (mm) | Hole diameter H11 (mm) | Length L (mm) | Groove form | Double shear (kN) | Hole preparation | Material | Reference standard |
|---|---|---|---|---|---|---|---|
| 2 | 2.0 | 10 | Full-length parallel | 2.6 | Drilled H11 | Steel, case hardened | DIN 1473 |
| 3 | 3.0 | 16 | Full-length parallel | 5.9 | Drilled H11 | Steel, case hardened | DIN 1473 |
| 4 | 4.0 | 20 | Full-length parallel | 10.5 | Drilled H11 | Steel, case hardened | DIN 1473 |
| 5 | 5.0 | 26 | Full-length parallel | 16.4 | Drilled H11 | Steel, case hardened | DIN 1473 |
| 6 | 6.0 | 32 | Full-length parallel | 23.6 | Drilled H11 | Steel, case hardened | DIN 1473 |
| 8 | 8.0 | 40 | Full-length parallel | 42.0 | Drilled H11 | Steel, case hardened | DIN 1473 |

Companion Standards
A complete specification for grooved pins (din 1471–1474) normally cites several documents: one for the geometry, one for the material or mechanical properties, and one for the finish. DIN 1473 is one of them, not all of them.
When to Specify DIN 1473
DIN 1473 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 pin to this standard in a non-standard size?
Parts built to DIN 1473 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 cold heading or turning.
Minimum order from 2,000 pieces; samples within 7 days of drawing approval.
