Sealed valve rivets

The sealed valve rivets are exclusive products developed by Nissen, that provide high water-tightness as sealed rivets and base material protection as valve type rivets.
They are suitable for equipment that needs higher water-tightness and more careful mounting, on top of normal rivet applications.

Nissen used light-weight and high corrosion-resistant titanium alloys for blind rivets, which are are applicable to vehicles, exhaust mufflers, lighting fixtures, roof fixing and grates. As the pioneers in production of blind rivets, Nissen will stay on the leading edge of the ‘connection’ technologies.

Nissen began business primarily in the production of iron wire and nails in 1949, during the post-war recovery period of Japan’s economy. Successful in making special nails, they began to export products to the US.
Focusing primarily on domestic nails produced for nail guns hardened to a high degree for driving into concrete and iron plates, they burnished their manufacturing technologies and methods, creating a complete process from drawing to producing nails and screws, and providing other finishing services.

Nissen’s blind rivets are an excellent alternative to welding and bolt fastening because they work from one side to fasten multiple items in a single operation. Saving labor, lowering costs and improving efficiency, they are making a great contribution to industry.

1) Open blind rivets: the standard type classified according to the flange head type round, countersunk or large head. A variety of colors are available as well.
2) Sealed: because the sealed blind rivet forms a bag shape without going completely through the material, they are ideal for preventing leaks and for sealed objects.
3) Valves: the shaft is formed with a uniquely developed shape for a wide range of joining applications with a high level of air tightness.
4) S bolts: strong, vibration-resistant and providing a high level of air tightness, the S bolt blind rivet is ideal for fastening critical safety locations.
