Introduction
Waterproof lantern rivets feature an rubber waterproof Blind Rivet and a sealed lock core structure, creating a 100% watertight fastener that completely resolves the common issues of water seepage, corrosion, and loosening in outdoor lighting fixtures and enclosures. The three-lobe lantern rivet design is ideal for thin sheets and brittle materials, allowing for quick single-sided installation. It provides long-lasting protection against rain and moisture while ensuring both strength and sealing. Compatible with common sizes ranging from 13/64“ to 5/16” to 1/4", It is heavy-duty fastening.it is a reliable solution for outdoor waterproof riveting.

.Ideal for Soft, Thin &Plastic Materials
Tri-firm rivets are designed for fastening soft and brittle materials, including plastics, composites, fiberglass and thin sheet materials, helping reduce pull-through and material deformation.
.Waterproof Tri-Firm Blind Rivets
Waterproof blind rivets with sealing washers are available for applications exposed to moisture, rain and outdoor environments, providing a sealed and secure fastening solution.
.Large Blind-Side Bearing Area
The expanded body of tri-fold rivets provides a larger bearing area than conventional blind rivets, helping distribute clamping force over a wider surface and improving joint stability.
.Aluminum Options
Our aluminum tri-firm blind rivets are available in different body and mandrel combinations, including aluminum, steel and stainless steel options for different strength, corrosion-resistance and application requirements.

Like other blind rivets, tri-firm rivets can be installed from one side of the assembly, making them suitable for applications where access to the rear side is limited or unavailable.
Application
.Automotive & Transportation
Tri-Firm blind rivets are suitable for fastening automotive plastics, composite panels, interior components and thin sheet materials, especially where one-side installation is required.
.Roofing & Building Panels
Waterproof blind rivets are ideal for roofing panels, metal sheets, aluminum panels and exterior building applications, providing secure fastening in exposed environments.
.Plastics & Composite Materials
The three-leg wtaterproof tri-fold blind rivets form clamping force over a larger area, making them suitable for plastics, fiberglass, composites and other soft materials.
.Electrical & HVAC Enclosures
Tri-firm blind rivets can be used for electrical enclosures, control cabinets, HVAC equipment and sheet metal assemblies , particularly where access to the rear side is limited.
Installation of Trifirn Blind Rivets
Tool Selection: We recommend using a standard electric or pneumatic rivet gun. For larger sizes of tri-firm blind rivets such as 5/16", we recommend ordering a custom-made rivet gun.
Hole Diameter Matching: The choice of hole diameter has a certain impact on waterproofing performance.
Pressure Control: Ensure that the dome rivet is fully severed and that the washer is properly compressed.
