TRI-FOLD BLIND RIVET HIGH STRENGTH

📌 Overview

The Stainless Steel Tri-Fold Blind Rivet (High Strength) is a premium heavy-duty fastening solution specifically engineered for soft, brittle, thin, and low-strength materials where conventional blind rivets may cause pull-through or material damage. During installation, the rivet body expands into three large folding legs (Tri-Fold expansion) on the blind side, creating an exceptionally wide bearing surface that distributes the load evenly and minimizes stress on the base material.

This unique expansion mechanism makes Tri-Fold rivets ideal for joining plastics, fiberglass, composites, aluminum sheets, sandwich panels, wood, and other lightweight materials. The large blind-side footprint provides excellent pull-out resistance, vibration resistance, and secure permanent fastening while preventing cracking or deformation of delicate materials.

Manufactured from Stainless Steel SS304 (A2) and SS316 (A4), or with a stainless steel body and stainless steel or hardened steel mandrel (depending on application), these rivets deliver excellent corrosion resistance, high tensile strength, and long service life in industrial, marine, transportation, and outdoor environments.

TRI-FOLD BLIND RIVET SOFT MATERIAL

📌 Overview

The Stainless Steel Tri-Fold Blind Rivet for Soft Material is a specialized blind fastening solution engineered for securely joining soft, brittle, thin, and low-density materials without causing pull-through, cracking, or surface damage. During installation, the rivet body expands into three large folding legs (Tri-Fold expansion) on the blind side, creating a wide bearing surface that evenly distributes the clamping load across the material.

Unlike conventional blind rivets, the Tri-Fold expansion mechanism significantly increases the contact area, making it ideal for fastening plastics, fiberglass (FRP), composites, plywood, sandwich panels, insulation panels, aluminum sheets, and lightweight materials. The result is a strong, vibration-resistant, and permanent joint while preserving the integrity of delicate materials.

Manufactured from Stainless Steel SS304 (A2) and SS316 (A4), or with a stainless steel body and stainless steel or hardened steel mandrel depending on application requirements, these rivets provide excellent corrosion resistance, reliable fastening performance, and long service life in indoor, outdoor, and marine environments.
