Waterproof Rivets
Product Overview
Waterproof rivets belong to the category of closed-type blind rivets and are fasteners specifically designed for applications requiring waterproofing, dustproofing, and high reliability. By employing a single-sided pulling operation, the rivet mandrel is completely enclosed within the sealed rivet body, while the entire tail section expands and deforms to seal the connection hole, fundamentally blocking fluid penetration pathways and delivering excellent air- and water-tight performance. This rivet not only boasts high shear strength but also supports convenient single-sided installation, eliminating the need for space on both sides, making it an ideal choice for outdoor and other specially constrained environments. It is widely applicable to various scenarios with sealing requirements, such as ships, containers, and steel structures.
Core Working Principle
The core waterproof mechanism of the waterproof rivet stems from its unique closed structure design. During single-sided pulling, the tensile force drives the mandrel to move, causing the tail section of the rivet body to expand and deform uniformly, tightly conforming to the inner wall of the connected component’s hole and forming the first line of defense. Simultaneously, the mandrel fully retracts into the sealed rivet shell, unlike traditional open-type rivets that leave exposed cut edges, thereby completely eliminating any pathway for fluids to penetrate through the mandrel’s fracture surface. This dual-sealing structure not only ensures secure fixation at the joint but also structurally blocks the ingress of water, moisture, dust, and other fluids, guaranteeing both air- and water-tightness.
Key Advantages
1. Superior Air- and Water-Tightness: After riveting, the tail section completely encloses the mandrel, and the expansion at the tail seals the hole, effectively blocking fluid penetration and meeting stringent waterproofing and dustproofing requirements, ensuring stable performance even in humid, dusty, or submerged conditions.
2. High Shear Strength: With outstanding shear resistance, it provides stable and reliable structural support for connections, suitable for high-strength structural applications and ensuring robust joint integrity.
3. Convenient Single-Sided Installation: Riveting can be completed with a single-sided pull, eliminating the need for space on both sides—particularly advantageous in confined spaces where double-sided operations are impractical, significantly enhancing installation efficiency and ease of use.
4. Enhanced Operational Safety: The mandrel remains fully enclosed within the rivet shell, avoiding the risk of “petal-like” fractures common in open-type rivets that could damage cables, injure personnel, or cause parts to fall off, thus improving long-term operational safety.
5. Strong Seismic Resistance: Lacking loose fragments inside, its seismic performance surpasses that of conventional open-type rivets; under continuous vibration, it effectively prevents mandrel loosening or joint failure, safeguarding the long-term stability of mechanical structures.
6. Excellent Corrosion Resistance: The sealed cavity isolates the mandrel from moisture and salt spray, slowing down electrochemical corrosion. When paired with stainless steel materials, it markedly extends the service life of both the fastener and the joined components, making it well-suited for harsh marine and outdoor environments.

Industry Pain Points Addressed
1. Solving the Problem of Leakage in Traditional Open-Type Rivet Joints: Conventional open-type rivets have exposed fracture surfaces through which fluids easily seep. The closed structure of waterproof rivets fundamentally blocks these pathways, completely eliminating leakage issues.
2. Improving Efficiency in Confined Spaces: Many specialized structural scenarios cannot accommodate double-sided riveting, leaving traditional rivets ill-suited. The single-sided installation design of waterproof rivets allows connections to be completed with just one side, greatly enhancing operational efficiency in tight spaces.
3. Mitigating Risks of Loose Connections Under Vibration: Ordinary open-type rivets tend to experience mandrel loosening or joint failure under sustained vibration. Waterproof rivets, lacking loose fragments internally and boasting superior seismic performance, effectively maintain structural integrity even in vibrating environments.
4. Alleviating Accelerated Fastener Corrosion in Harsh Conditions: In outdoor and marine environments, moisture and salt spray often accelerate corrosion of rivet mandrels. The sealed cavity of waterproof rivets isolates the mandrel from external corrosive agents, slowing down corrosion and extending the service life of fasteners.
5. Eliminating Safety Hazards Associated with Traditional Rivet Fractures: The “petal-like” fracture edges of open-type rivets can scratch cables, injure personnel, or even cause fragments to detach. The fully enclosed mandrel design of waterproof rivets completely eliminates these safety risks, enhancing overall equipment safety.
