Specification summary of ISO 1051 as applied to solid rivets: the dimensions the standard fixes, the full size range supplied, and the related designations commonly cross-referenced.
ISO 1051 — Scope
The table below lists the dimensions catalogued for solid rivets under ISO 1051. The scope of ISO 1051 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 ISO 1051. Tolerances for this part are the limits shown against each dimension in the table.

Equivalent Standards
Where direct equivalents exist (ISO ↔ DIN, ISO ↔ ASME), they are listed on the parent Solid Rivets page.
Always confirm against the dimensions on this page, since some "equivalent" standards differ in tolerances and head geometry.
Companion Standards
A complete specification for solid rivets normally cites several documents: one for the geometry, one for the material or mechanical properties, and one for the finish. ISO 1051 is one of them, not all of them.
Custom manufacturing · Made to drawing
Need a rivet to this standard in a non-standard size?
Parts built to ISO 1051 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 drawing.
Minimum order from 2,000 pieces; samples within 7 days of drawing approval.
