Rivetking 25N75RC8AP/1100 Countersunk Aluminum Solid Rivet

Product Description

The RIVETKING 25N75RC8AP/1100 is a countersunk head aluminum solid rivet designed for permanent fastening applications where a flush surface finish is required. The body diameter measures 0.25 inches with a length under head of 0.75 inches. Manufactured from Grade 1100 aluminum, this rivet provides reliable shear strength in lightweight assemblies. It is installed using a rivet set and bucking bar by sheet metal workers, aircraft maintenance technicians, and general fabricators working with aluminum structures and panels.

This rivet is suited for residential and light commercial fabrication, HVAC ductwork assembly, sheet metal paneling, and general manufacturing where a flush surface is required after installation. The 78-degree countersunk head angle seats cleanly into pre-drilled countersunk holes, allowing mating surfaces to sit flat without protrusion. Grade 1100 aluminum offers good corrosion resistance and workability in non-structural and lightly loaded joint applications.

Key Features

• Countersunk head at 78 degrees for flush surface installation
• Grade 1100 aluminum construction for corrosion resistance and easy driving
• 0.25 inch body diameter suits standard countersunk hole patterns
• 0.75 inch length under head accommodates typical sheet metal stack-ups
• Solid rivet construction provides permanent, vibration-resistant fastening

Compatibility

Designed as an OEM-style solid rivet for use in aluminum sheet metal assemblies requiring a countersunk flush-head fastener with a 0.25 inch body diameter.

Installation Notes

Installation requires a rivet set matched to the countersunk head angle and a bucking bar or rivet gun rated for solid rivets. Ensure the receiving material is drilled and countersunk to the correct angle and diameter before driving. Power down or de-energize any adjacent electrical components before beginning fastening work in panel or enclosure applications. Do not substitute solid rivets for blind rivets in applications where both sides of the joint are not accessible.
