Blind Rivet – Closed End Dome Head Technical Datasheet

Product Overview

Blind Rivet Closed End Dome Head (also known as Sealed Blind Rivets) are designed to provide strong permanent fastening while preventing the passage of liquids, moisture, dust, air, and contaminants through the rivet body. Unlike open-end blind rivets, the mandrel is completely enclosed within the rivet body, creating a sealed joint after installation.

Closed End Dome Head Blind Rivets are widely used in applications requiring water-tight or air-tight joints, including electrical enclosures, HVAC equipment, automotive components, sheet metal fabrications, appliances, marine equipment, and outdoor installations.
