For blind pop rivet, ISO 15977 is the governing document for the dimensions listed below. Mechanical and performance requirements for this part family are set by its own standards, not by the bolt and screw property-class documents.
ISO 15977 — Scope
ISO 15977 is "Open end blind rivets with break pull mandrel and protruding head — AlA/St".
Material, property class, surface finish and packaging are governed by separate documents — ISO 898-1 and ISO 898-2 for mechanical property classes, ISO 4042 for electroplated finishes.
Tolerance & Product Grades
ISO 15977 does not divide blind pop rivet — gb/t 12618 / iso 15977 (series 098) into product grades. Tolerances are given as limits on the individual dimensions in the table.
Where a general-tolerance class is cited on the drawing instead, it applies to the dimensions not otherwise toleranced.
Dimensions Specified by ISO 15977
| Nominal diameter (mm) | Grip range (mm) | Cap diameter dk (mm) | Free length L (mm) | Body / mandrel material | Reference standard |
|---|---|---|---|---|---|
| 2.4 | 0.5~3.0 | 5.0 | 7.0 | Aluminum / steel | ISO 15977 / DIN 7337 |
| 3.0 | 0.5~4.0 | 6.0 | 8.0 | Aluminum / steel | ISO 15977 / DIN 7337 |
| 3.2 | 0.5~6.0 | 6.4 | 10.0 | Aluminum / steel | ISO 15977 / DIN 7337 |
| 4.0 | 0.5~6.0 | 8.0 | 12.0 | Aluminum / steel | ISO 15977 / DIN 7337 |
| 4.8 | 0.5~8.0 | 9.5 | 14.0 | Aluminum / steel | ISO 15977 / DIN 7337 |
| 5.0 | 1.0~10.0 | 10.0 | 16.0 | Stainless / stainless | ISO 15977 / DIN 7337 |
| 6.0 | 1.5~12.0 | 12.0 | 18.0 | Stainless / stainless | ISO 15977 / DIN 7337 |
Equivalent Standards
Where direct equivalents exist (ISO ↔ DIN, ISO ↔ ASME), they are listed on the parent Blind Pop Rivet — GB/T 12618 / ISO 15977 (Series 098) page.
Always confirm against the dimensions on this page, since some "equivalent" standards differ in tolerances and head geometry.
When to Specify ISO 15977
Choose ISO 15977 for international engineering work and OEM supply where ISO standards are the contractual reference. It is the default modern specification for blind pop rivet — gb/t 12618 / iso 15977 (series 098).
Custom manufacturing · Made to drawing
Need a rivet to this standard in a non-standard size?
Parts built to ISO 15977 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.
