Rivetking 25N125RC8AP/1100 Countersunk Aluminum Solid Rivet

Product Description

The RIVETKING 25N125RC8AP/1100 is a countersunk head solid aluminum rivet designed for permanent mechanical fastening applications. It features a 0.25-inch body diameter and a 1.25-inch length under the head, with a 78-degree countersunk head angle that seats flush with the work surface when properly driven. Made from Grade 1100 aluminum, this rivet offers good corrosion resistance and is easy to set without specialized tooling. It is installed by licensed tradespeople and skilled technicians wherever a clean, flush fastener profile is required in aluminum or light-gauge assemblies.

This solid rivet is suited for use in sheet metal fabrication, HVAC ductwork assembly, electrical enclosure manufacturing, and general mechanical construction where a permanent, flush-head fastener is specified. The countersunk profile makes it appropriate for panels and surfaces where a protruding head would interfere with fit, airflow, or mating components. Grade 1100 aluminum is well suited to applications where high strength is not the primary requirement but corrosion resistance and workability are priorities.

Key Features

• 0.25-inch body diameter for standard fastening applications
• 1.25-inch length under head accommodates typical multi-layer sheet assemblies
• 78-degree countersunk head angle seats flush with the material surface
• Grade 1100 aluminum construction provides corrosion resistance and easy setting
• Solid rivet design creates a permanent, vibration-resistant mechanical joint

Compatibility

Designed as a standard countersunk solid aluminum rivet for use in sheet metal, HVAC ductwork, electrical enclosures, and light fabrication assemblies requiring a 0.25-inch body diameter flush-head fastener.

Installation Notes

Solid rivets require a bucking bar and rivet hammer or a dedicated rivet set for proper installation. The receiving hole should be drilled to the correct clearance diameter for a 0.25-inch body rivet before insertion. Always de-energize and lock out any equipment before fastening into assemblies containing electrical components. Follow applicable building and mechanical codes for the specific application and material stack-up.
