Companion Standards
A complete specification for blind pop rivet — gb/t 12618 / iso 15977 (series 098) normally cites several documents: one for the geometry, one for the material or mechanical properties, and one for the finish. GB/T 12618 is one of them, not all of them.
When to Specify GB/T 12618
Choose GB/T 12618 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 GB T 12618 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.
