Blind Rivet – Multigrip Large Flange Technical Datasheet
Product Overview
Multigrip Large Flange Blind Rivets are designed to provide a wide grip range while offering increased bearing surface and superior pull-through resistance compared to standard dome head blind rivets. The large flange head distributes the clamping force over a larger area, making these rivets particularly suitable for thin sheet materials, plastics, composites, and applications where enhanced load distribution is required.
Manufactured with an aluminium body and zinc-plated steel mandrel, these blind rivets help reduce inventory by replacing multiple grip ranges with a single fastener. They provide reliable installation, excellent hole-filling capability, and consistent fastening performance across a wide range of industrial applications.

Frequently Asked Questions
What is a multigrip blind rivet?
A multigrip blind rivet is a blind rivet designed to accommodate a much wider grip range than conventional blind rivets, allowing one rivet size to replace several standard grip ranges.
What is the advantage of a large flange head?
The large flange head distributes the clamping load over a larger surface area, reducing the risk of pull-through and improving fastening performance in thin or soft materials.
Can multigrip rivets be installed using standard rivet tools?
Yes. Most multigrip blind rivets can be installed using standard manual, pneumatic, or battery-operated blind rivet tools.
Are multigrip rivets suitable for oversized holes?
Yes. One of their primary advantages is excellent performance in oversized, slotted, and irregular holes.
What material combinations are available?
Common combinations include Aluminium/Steel, Steel/Steel, Stainless Steel/Stainless Steel, and Aluminium/Stainless Steel.
Are multigrip rivets structural rivets?
No. Multigrip rivets are designed primarily for extended grip capability and hole compensation. For high-strength structural applications, structural blind rivets such as Monobolts or Interlock rivets are recommended.
Are multigrip rivets watertight?
No. Open end blind rivets are not designed to provide a watertight seal. For sealing applications, closed end blind rivets are recommended.
