Rivetking 25N62RC9SP Solid Rivet Countersunk Steel 1/4 in

Product Description

The RIVETKING 25N62RC9SP is a solid rivet with a countersunk head profile, manufactured from uncoated steel. It features a 1/4 inch body diameter and a 5/8 inch length under the head, with a 90-degree countersunk head angle that sits flush with the mating surface when set. Solid rivets provide a permanent, high-strength mechanical fastener suitable for structural and general fabrication applications. This rivet is supplied uncoated, making it appropriate for assemblies where a secondary coating or paint will be applied after installation. Licensed trades and fabricators working in sheet metal, HVAC ductwork, equipment enclosures, and structural assemblies commonly specify solid rivets for joints that require permanent retention without threaded fastener loosening concerns.

This solid countersunk rivet is suited for flat or flush-mount installations where the fastener head must sit level with or below the workpiece surface. The 90-degree head angle is a standard countersunk geometry compatible with pre-drilled or countersunk holes in steel, aluminum, and similar structural materials. It is commonly used in HVAC fabrication, electrical enclosure assembly, ductwork, and light structural metalwork where flush surfaces and permanent joints are required.

Key Features

• Solid rivet construction provides a permanent, high-strength mechanical joint
• Countersunk head with 90-degree angle for flush surface installation
• 1/4 inch body diameter fits standard 1/4 inch drilled or punched holes
• 5/8 inch length under head accommodates typical material stack thicknesses
• Uncoated steel finish compatible with post-installation coating or paint processes

Compatibility

Designed as a standard solid countersunk rivet for use in steel, aluminum, and similar structural substrates requiring a flush 90-degree countersunk head fastener with a 1/4 inch body diameter.

Installation Notes

Solid rivets require a bucking bar and rivet hammer or hydraulic squeezer for proper installation by a qualified fabricator or sheet metal mechanic. Power down all associated electrical systems and ensure structural panels are fully supported before driving rivets in equipment assemblies. Pilot hole diameter should match the rivet body diameter per applicable fastener and structural codes. Do not substitute solid rivets for blind rivets in applications where both sides of the joint are not accessible.
