Nippon Seisen was founded in 1949, during Japan's economic recovery period, initially focusing on the production of iron wire and nails. Since then, it has expanded its business through the manufacture of special nails and has been involved in exports to the United States from an early stage.

Meanwhile, for the domestic market, our main product is nails for automatic nail guns (for concrete and steel plates, with advanced heat treatment), and we have honed our integrated manufacturing technology from wire drawing to nail making, screw processing, and finishing.

Furthermore, in 1969, we succeeded in domestically producing blind rivets that take advantage of the characteristics of the materials used. Leveraging our tradition and commitment to craftsmanship, we accurately understand our customers' needs and aim to provide "high variety, small quantities, high quality, short delivery times, fair prices, and stable supply" that can only be achieved through domestic production. We produce products using a wide range of metal materials, including iron, aluminum, stainless steel, copper, and titanium.

Nippon Seisen will continue to pursue metal fastening technology and strive to develop fastener products that are best suited to our customers' applications.

Blind rivets are components used to fasten (fix) two or more plates or plates to irregularly shaped components from one side, as an alternative to welding or bolting. Even if you cannot reach the back of the base material to be fastened (because it is a blind rivet), fastening can be done easily and quickly with a special tool.

Open type: Standard type with flange head shapes including round head, countersunk head, and large head. Colored options are also available.
Shielded type: This rivet is suitable for fastening waterproof and sealed areas because the rivet portion does not penetrate the metal but is enclosed in a bag-like shape.
Valve type: This rivet features a unique shape on the rivet body to ensure a wide fastening range and high airtightness.
S-bolts: These rivets are ideal for fastening critical safety components due to their high strength, high vibration resistance, and high airtightness.

Nippon Seisen has become the first company in Japan to mass-produce titanium blind rivets.
Titanium is lighter than other metals, has excellent corrosion resistance, and is highly resistant to corrosion in rust-prone environments and galvanic corrosion. It can be used in a wide range of fastening components and parts, including automobiles, motorcycle mufflers, lighting equipment, personal computers, roofs, window grilles, and retractable gates.
