Rivetking 18N125RC9SP Countersunk Solid Rivet Steel

Product Description

The RIVETKING 18N125RC9SP is a countersunk solid rivet designed for permanent mechanical fastening in metal fabrication, structural assembly, and maintenance applications. The rivet features a 3/16 inch body diameter, a 1-1/4 inch length under the head, and a 90-degree countersunk head angle that sits flush with the mating surface when properly set. The uncoated steel construction provides strength suited to general-purpose fastening tasks. This part is typically installed by sheet metal workers, HVAC fabricators, structural technicians, and maintenance trades working with steel assemblies.

This solid rivet is well suited for residential and light commercial HVAC ductwork fabrication, electrical panel enclosure assembly, and general structural metalwork where a flush, permanent fastener is required. The countersunk profile makes it appropriate for applications where a protruding head would interfere with clearances or surface finish. No specific model compatibility is required for a consumable fastener of this type.

Key Features

• 3/16 inch body diameter for standard-clearance hole fitment
• 1-1/4 inch length under head suits moderate material stack thicknesses
• 90-degree countersunk head angle allows flush installation
• Uncoated steel construction provides solid mechanical strength
• Solid rivet design creates a permanent, vibration-resistant joint

Compatibility

Designed as a general-purpose countersunk solid rivet for use in steel fabrication, HVAC ductwork, enclosure assembly, and structural metalwork applications requiring a 3/16 inch fastener with a flush head profile.

Installation Notes

Solid rivets require a bucking bar and rivet hammer or a dedicated rivet squeezer for proper setting - a pull-type rivet tool is not compatible with solid rivet stock. Ensure the mating hole is drilled or punched to the correct clearance diameter for a 3/16 inch body before driving. De-energize any associated electrical assemblies and follow applicable codes before performing fastening work on energized enclosures or structural components.
