Rivetking. 18N50RRDAP/1100 Solid Rivet Aluminum Round Head

Product Description

The RIVETKING. 18N50RRDAP/1100 is a solid aluminum rivet with a round head profile, designed for permanent mechanical fastening in sheet metal, fabrication, and general assembly applications. The body diameter measures 3/16 inches and the length under the head is 1/2 inch, making it suited for thin-to-medium material stacks. Constructed from 1100-series aluminum, it offers good corrosion resistance and a clean uncoated finish. This rivet is installed using a rivet set and hammer or a pneumatic rivet hammer, and is a standard choice for electricians, HVAC fabricators, duct installers, and general sheet metal workers who need a reliable, non-threaded permanent fastener.

This solid rivet is appropriate for light-duty structural and non-structural fastening tasks across residential and commercial trade work. Typical applications include duct fabrication, electrical panel and enclosure assembly, bracket mounting, and metal-to-metal joining where a flush or rounded head profile is acceptable. The 1100-series aluminum alloy is well suited for applications where the fastener may be exposed to moisture or mild chemical environments. It is sold individually, making it accessible for small-quantity repair work as well as bulk procurement for production use.

Key Features

• 3/16 inch body diameter for standard sheet metal and fabrication hole patterns
• 1/2 inch length under head accommodates thin-to-medium material stack-ups
• 1100-series aluminum construction provides corrosion resistance and light weight
• Uncoated finish is compatible with painted, primed, or bare metal surfaces
• Round head profile distributes clamping load evenly across the mating surface
• Does not meet military specifications - intended for commercial and trade applications

Compatibility

Designed as a standard solid rivet for commercial and trade fastening applications involving aluminum or compatible sheet metal assemblies. No specific model or system compatibility data was provided by the manufacturer for this part.

Installation Notes

Solid rivets are installed by a sheet metal worker, HVAC fabricator, or general trades technician using a rivet set, bucking bar, and hammer, or a pneumatic rivet hammer. Ensure the mating hole diameter matches the 3/16 inch body diameter before driving. Always de-energize any nearby electrical equipment and follow applicable safety protocols before beginning fastener installation in live assemblies. Do not substitute solid rivets for blind rivets in applications where rear access is not available.
