Clean Flush Appearance
Designed for blind fastening where only one side is accessible, improving assembly efficiency and simplifying installation.
Standard: ASME/ANSI B18.30.1M-2

ASME/ANSI B18.30.1M-2 100° & 120° Countersunk Head Style Break Mandrel Blind Rivets (Metric Series) are metric blind rivets designed for flush surface fastening. Featuring either a 100° or 120° countersunk head, they sit flush with the workpiece after installation, providing a clean appearance while reducing interference and improving aerodynamic performance.
The break mandrel design enables installation from one side only, making these rivets ideal for enclosed structures, sheet metal fabrication, maintenance work, and assemblies where rear-side access is impossible.


Designed for blind fastening where only one side is accessible, improving assembly efficiency and simplifying installation.
Break mandrel construction allows quick installation from one side, reducing assembly time and simplifying work in confined spaces.
Provides consistent clamping performance across sheet metal, aluminum, stainless steel, and other industrial materials.
It specifies metric break mandrel blind rivets with 100° or 120° countersunk heads.
It provides a flush surface for improved appearance and reduced interference.
Aluminum, steel, stainless steel, and mixed-material combinations.
Yes. Custom dimensions and grip ranges are available.
