Rivetking 18N75RRDSP Countersunk Solid Rivet Steel

Product Description

The RIVETKING 18N75RRDSP is a countersunk solid rivet designed for permanent mechanical fastening in metal fabrication, structural assembly, and maintenance applications. The body diameter measures 3/16 inches with a 3/4 inch length under head, and the countersunk head is formed at a 90-degree angle to allow a flush finish on the mating surface. Constructed from uncoated steel, this rivet delivers solid shear strength for load-bearing joints. It is installed by licensed tradespeople, maintenance technicians, and skilled fabricators who require a dependable, non-threaded fastener solution.

This solid rivet suits residential and light commercial applications where a flush surface is required after installation. Common use cases include HVAC ductwork assembly, equipment panel fabrication, structural brackets, and general sheet metal work. The 90-degree countersunk head seats cleanly into a pre-drilled countersunk hole, eliminating head protrusion and reducing snagging risk in finished assemblies. This rivet does not meet military specifications and is intended for standard commercial and trade applications.

Key Features

• 3/16 inch body diameter for use in standard countersunk hole preparations
• 3/4 inch length under head accommodates typical sheet metal stack-ups
• 90-degree countersunk head angle delivers a flush, low-profile finish
• Uncoated steel construction provides solid shear and tensile performance
• Solid rivet design creates a permanent, vibration-resistant mechanical joint

Compatibility

Designed as an OEM-style solid rivet replacement for countersunk fastener applications in standard steel fabrication and sheet metal assembly work.

Installation Notes

Installation is performed by fabricators, sheet metal mechanics, or maintenance technicians using a rivet set and bucking bar or appropriate pneumatic rivet tooling. Ensure the mating material is pre-drilled and countersunk to the correct 90-degree angle and hole diameter before driving the rivet. Always wear appropriate eye protection during riveting operations. Inspect the driven head for full material upset and flush seating before considering the joint complete.
