Blind Rivet – Multigrip CSK Head Technical Datasheet
Product Overview
Multigrip Open End Countersunk (CSK) Head Blind Rivets are designed to fasten a wide range of material thicknesses using a single rivet size, reducing inventory requirements and simplifying assembly operations. The countersunk head design provides a flush surface finish after installation, making these rivets suitable for applications where aesthetics, clearance, or functional requirements demand a smooth surface.
These rivets are widely used in sheet metal fabrication, electrical control panels, enclosures, HVAC equipment, transportation, furniture, and general industrial assembly 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 countersunk head blind rivet?
A countersunk head allows the rivet to sit flush with the surface of the material, providing improved aesthetics and clearance.
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.
