Rivetking 25N50RC9SP Countersunk Steel Solid Rivet

Product Description

The RIVETKING 25N50RC9SP is a countersunk steel solid rivet with a 0.25-inch body diameter and a 0.5-inch length under the head. The head geometry features a 90-degree countersunk angle, allowing it to sit flush with the mating surface after installation. Solid rivets of this type are driven with a rivet hammer or pneumatic rivet gun and require access to both sides of the joint. This fastener is suited for structural and mechanical assembly work performed by millwrights, sheet metal workers, ironworkers, and maintenance technicians working in fabrication or repair environments.

This rivet is used in metal-to-metal joining applications where a flush surface finish is required after driving. The countersunk head profile makes it well suited for panels, brackets, and structural assemblies where protruding fastener heads would interfere with fit or function. The 0.25-inch body diameter accommodates standard pre-drilled or punched holes sized to match that shank. It is appropriate for both light structural and general mechanical assembly tasks in shop and field settings.

Key Features

• 0.25-inch body diameter fits standard quarter-inch rivet holes
• 0.5-inch length under head accommodates typical sheet and plate stack-ups
• 90-degree countersunk head angle seats flush with mating surface after driving
• Steel construction provides strength suitable for mechanical and structural assemblies
• Solid rivet design requires no mandrel and leaves no hollow core

Compatibility

Designed as an OEM-style replacement or standard solid rivet for use in any application requiring a 0.25-inch body diameter countersunk steel solid rivet with a 0.5-inch length under head.

Installation Notes

Installation of solid rivets requires access to both faces of the joint - one side to drive the rivet and one side to buck or back-up the head. A rivet hammer, pneumatic hammer, or rivet set and bucking bar are typical tools for this operation. Ensure the mating hole is properly sized to the 0.25-inch shank before driving to avoid joint damage. Follow applicable structural fastening codes and shop procedures when using solid rivets in load-bearing assemblies.
