Product Overview
The Tri-fold Blind Rivet, also known as a Lantern or Bulb-tite rivet, is a specialized fastener designed specifically for applications involving soft, brittle, or thin materials. Unlike standard blind rivets, the body of a Tri-fold rivet splits into three distinct "petals" on the blind side during installation. This creates an extra-wide footprint that distributes the clamping force over a larger surface area, preventing pull-through or material cracking.
Key Features & Benefits
Large Bearing Surface: The three-folded legs provide a massive blind-side surface area, making it ideal for fastening plastics, fiberglass, composites, and thin sheet metals.
Superior Load Distribution: Minimizes the risk of damaging fragile materials or "pulling through" soft substrates.
Vibration Resistance: The structural design ensures a secure, rattle-free joint even in high-vibration environments like automotive or HVAC systems.
Multi-Grip Capability: Offers a wide grip range, allowing one rivet size to be used for various material thicknesses, reducing inventory costs.
Optional Weatherproofing: Available with integrated EPDM washers to provide a moisture-proof seal, perfect for roofing and outdoor applications.
Technical Specifications
Materials: High-strength Aluminum Alloy (Body) / Steel or Aluminum (Mandrel).
Head Styles: Dome Head, Large Flange, or Countersunk.
Common Sizes: 4.0mm (5/32"), 4.8mm (3/16"), 6.4mm (1/4").
Finish: Plain, Anodized, or Zinc Plated for enhanced corrosion resistance.
Typical Applications
Automotive: Plastic bumpers, interior trim, spoilers, and trailer skinning.
Construction: Metal roofing, cladding, and gutter installation.
Renewable Energy: Solar panel mounting on thin-gauge metal roofs.
Manufacturing: Plastic crates, furniture, and fiberglass boats.
