Closed End Blind Rivet
This product features a closed-loop core-pulling structure. The nail body is sealed at the end, forming a sealed structure after riveting, providing waterproof and corrosion-resistant protection. After the core rod breaks, the sealed end adheres to the workpiece, ensuring a secure connection. Suitable for outdoor and waterproof applications. All series are readily available, with surface treatments such as galvanizing and Dacromet coating for rust prevention. Quality control is ensured, and environmental regulations are met. Compliance documentation is available, and customization of non-standard sizes and waterproof ratings is supported.
