Info
Blind Rivets (often referred to as breakstem rivets) allow two or more similar or different materials to be joined
together from one side of the application.
Available in a combination of diameters, grip-ranges and materials, sealed large head rivets are a highly versatile
and cost effective, industry proven joining method. This head style provides double the bearing area compared to
dome head rivets, they are designed for applications where a soft or brittle material is assembled to a rigid support
material. The sealed design ensures the joint is moisture and pressure tight, completely sealed to fluids, avoiding
leakage of liquids or vapours. The mandrel is completely retained within the head, reducing the risk of electrical
shorting issues or in service vibrations.
Installation is simple, with tooling ranging from cheap pistol-grip style guns to air-powered placement equipment
suitable for production line work.
Applications include, automotive, aerospace, furniture, restoration, sheet metal fabrication etc.
