Operating requirements and torque strength of closed end self sealing rivets

- Apr 18, 2019-

Closed end self sealing rivets can be roughly divided into open type, closed type, double drum type and single drum type during operation. The following descriptions are given for each model. Countersunk type blind rivets: Riveting of riveted parts that require a smooth and beautiful surface after riveting. Double drum type blind rivet: When riveting, the nail core pulls the end of the rivet body into a double drum shape, clamping the two structural parts to be riveted, and reducing the pressure acting on the surface of the structural part.


Closed self-sealing rivets are mainly used for riveting various thin structural parts in various vehicles, ships, construction, machinery, electronics and other industries. Large brim blind rivet: The rivet has a significantly larger diameter of the aluminum cap than the conventional blind rivet. The rivet has a larger contact area when riveted with the connecting piece, and has a stronger supporting surface to enhance the torque. Strength, able to withstand higher radial tension.


Closed self-sealing rivets are suitable for fastening soft, fragile surface materials and extra large holes, which increase the brim diameter for special protection of soft materials. Closed blind rivets: Designed to wrap the mandrel head after riveting, it is ideal for a wide range of applications with waterproofing requirements. With high shear, anti-vibration and high pressure resistance.
