Copper countersunk-head rivets — reliable, corrosion-resistant fasteners for conductive and structural joins Key benefits Corrosion-resistant copper construction protects joints in humid or corrosive environments. Excellent electrical conductivity makes these rivets suitable where current flow or grounding is required. Cold-formable design and straightforward installation produce a strong, permanent closure without heat. Can be hardened in some applications to increase shear and tensile strength where needed. Features and performance Material: high-quality copper for long-term corrosion resistance and stable conductivity. Head type: countersunk head provides a flush finish when installed in countersunk holes. Forming: designed for cold forming; the rivet tail is deformed (struck, pressed or spun) after insertion to secure the joint. Optional hardening: in certain use cases the rivet can be hardened to enhance mechanical performance. How it solves problems Eliminates the need for solder or welding when a conductive, permanent joint is required. Flush countersunk head reduces snagging and interference with mating parts. Cold forming enables installation without thermal stress to surrounding materials or components. Installation and compatibility Install by inserting rivet into the countersunk hole, then strike, press or spin the rivet shank end to form the blind head and lock the joint. Compatible with common cold-forming methods and manual or press-based fastening operations that deform the rivet tail. Suitable for joining thin-to-medium sheets and components where a flush, conductive, corrosion-resistant fastener is required. Typical use scenarios Electrical assemblies: securing busbars, terminal plates or conductive brackets where reliable electrical contact and corrosion resistance are required. Instrumentation and electronics enclosures: fastening thin sheet components while maintaining a flush surface and avoiding heat damage. Low-load structural joins in marine or outdoor equipment where copper’s corrosion resistance and conductivity are advantageous. What to expect A permanent, flush fastener that maintains electrical continuity and resists corrosion. Simple, cold-installation process using standard forming or peening methods. Option to increase mechanical strength by applying a suitable hardening treatment in compatible applications. If you need a corrosion-resistant, conductive, flush-mounted rivet that installs without heat and can be cold-formed or hardened for greater strength, these copper countersunk rivets provide a practical, dependable solution.
