Rivetking 18N87RRDSP Countersunk Solid Rivet 3/16 in Steel

Product Description

The RIVETKING 18N87RRDSP is a countersunk solid rivet designed for permanent fastening in metal fabrication, structural assembly, and general trade applications. It features a 3/16-inch body diameter and a 7/8-inch length under the head. The 90-degree countersunk head profile sits flush with the mating surface once set, making it a reliable choice where a flat finish is required. Constructed from uncoated steel, this rivet delivers solid shear and tensile strength suited to a wide range of industrial and mechanical fastening tasks. Installation requires a rivet hammer or pneumatic rivet set and bucking bar for proper heading.

This solid rivet is well-suited for light structural, sheet metal, and equipment assembly work in both shop and field environments. It fits typical applications found in HVAC unit fabrication, electrical enclosure assembly, equipment bracket mounting, and general mechanical trades. Its countersunk geometry is appropriate wherever a low-profile head is needed to avoid interference with mating components or surface coverings. Single-piece solid construction ensures a permanent, vibration-resistant joint.

Key Features

• Countersunk head with 90-degree angle for flush-mount installation
• 3/16-inch body diameter for standard structural fastening applications
• 7/8-inch length under head provides adequate grip range for typical sheet thickness stacks
• Uncoated steel construction for consistent shear and tensile performance
• Solid rivet design creates a permanent, vibration-resistant joint

Compatibility

Designed as a standard countersunk solid rivet for use in sheet metal, structural, and mechanical assemblies requiring a 3/16-inch diameter permanent fastener with a flush 90-degree head profile.

Installation Notes

Solid rivets are installed by licensed tradespeople or qualified technicians using a rivet hammer, pneumatic rivet gun, or hand-setting tools paired with a bucking bar on the opposite side. Ensure the work piece is fully supported and hole diameter is matched to the 3/16-inch shank before driving. De-energize any equipment and follow applicable shop safety procedures before beginning fastening operations. Do not substitute solid rivets for blind or semi-tubular fasteners in applications where they are specifically required.
