Rivetking. 18N25RFLAP/1100 Solid Rivet Aluminum Flat Head

Product Description

The RIVETKING. 18N25RFLAP/1100 is a solid aluminum rivet with a flat head profile, designed for permanent mechanical fastening in light-duty structural and sheet-metal assembly work. The body diameter measures 3/16 inches with a length under head of 1/4 inch. Manufactured from Grade 1100 aluminum, this rivet offers good corrosion resistance and workability in applications where high strength is not the primary requirement. The uncoated finish leaves the aluminum in its natural state, making it suitable for environments where coating compatibility or weight savings are priorities. Installation is performed by tradespeople and fabricators using standard rivet sets and bucking bars.

This rivet is used in light-gauge sheet metal fabrication, HVAC ductwork assembly, aluminum panel joining, and general maintenance applications. Its flat head profile sits flush or near-flush against the work surface, making it appropriate for assemblies where protrusion must be minimized. Grade 1100 aluminum is a commercially pure aluminum alloy commonly specified where formability and corrosion resistance matter more than tensile strength. This part is sold individually and is suitable for small-quantity repair or replacement work.

Key Features

• 3/16 inch body diameter for standard light-gauge fastening applications
• 1/4 inch length under head accommodates thin-stack sheet metal assemblies
• Grade 1100 aluminum construction provides natural corrosion resistance
• Flat head profile minimizes surface protrusion after installation
• Uncoated finish - no added coatings that could interfere with mating surfaces
• Does not meet military specifications - suited for commercial and general trade use

Compatibility

Designed as a standard solid rivet replacement for light-duty aluminum fastening applications in HVAC ductwork, sheet metal fabrication, and general mechanical assembly.

Installation Notes

Solid rivets require a rivet set and bucking bar for proper installation and should be driven with a pneumatic or hand rivet hammer. Always ensure the combined material thickness of the joint falls within the grip range before selecting rivet length. Power down or de-energize any associated equipment before fastening in proximity to electrical or HVAC components. Follow applicable sheet metal fabrication standards and shop safety procedures during installation.
