Railway-related products: Rail screws

We offer screws with high precision and strong threads produced by the hot rolling method!

At Teikoku Seibou, a leading company in rail fastening component manufacturing, we handle "rail screws." The intended uses are for fixing rails and fastening tie plates. We have cut threads to increase the pull-out resistance of the screws. With the spread of synthetic sleepers, there are often cases where screws with thinner shaft diameters or smaller head diameters are produced, and the shapes are changed depending on the usage location, compared to conventional rail screws. Once we receive your drawings, we will start with mold design and proceed to manufacturing, so please feel free to consult with us. 【Features】 ■ High-precision and strong threaded parts due to hot rolling method ■ Threads are cut to increase the pull-out resistance of the screws ■ JIS mark certification product (JIS E1109) *For more details, please refer to the PDF materials or feel free to contact us.

Railway-related products: resin-coated bolts for electrical contact and anti-corrosion.

Bolts treated with coatings such as nylon-based and epoxy-based.

Electrolytic corrosion is a phenomenon where metal rapidly dissolves due to the flow of electricity from natural phenomena on the surface of the metal. Iron structures are painted, and this paint contains a lot of zinc, which provides rust prevention effects. However, there are many areas of corrosion on bolts that have been treated with hot-dip galvanized coating, especially in places that experience repeated wetting and drying or have high humidity. To help address these issues, we also sell bolts that have been coated with nylon-based and epoxy-based treatments. *For urgent or emergency cases, or for technical inquiries, please contact us directly through our website.*

Special screw type series of swivel eye bolts (Unified, fine thread, etc.)

Rudd's series of swivel eye bolts, capable of accommodating special screws such as unify, wit, and pipe threads!

The JIS type eye bolts commonly used in the manufacturing and construction industries have a ring that rotates in the direction of the load, causing the screw to loosen and creating a gap with the mating surface, making lifting operations with these eye bolts very dangerous. Therefore, our rotating eye bolts are widely used by customers in various industries. However, when the mating side has screw taps such as "inch screws" or "parallel pipe threads," it is often unavoidable to use JIS type eye bolts with special screw specifications. Please consider this before an accident occurs. 【Features】 - Compatible with various screw standards (metric screws, inch screws, pipe threads, etc.) - Rich variety *For more details, please contact us or download the catalog.

Regarding the selection of sheet colors for waterproofing functionality.

Knowledge of Boss Color Selection: Preventing water intrusion from the outside with the adoption of sheet color!

【Before】 Eye bolts are used to lift and move various heavy enclosures and machinery. However, to install them on the ceiling of the enclosure or machinery, measures are necessary to prevent water ingress from the ceiling in environments where waterproofing is required. ↓ 【After】 In the case of metal enclosures used on ships, it becomes possible to prevent external water ingress, such as water leaks from the ceiling, by not only using eye bolts but also adopting a sheet color between the enclosure and the eye bolt to ensure waterproofing. *For more details, please refer to the catalog or feel free to contact us.*

Selection of green bolts to improve tightening workability.

Knowledge for selecting other accessories and parts: Improved workability with washer-integrated design!

【Before】 ■Green Bolt The Green Bolt is a widely used component for housings and panels as a screw for earth terminals. It is a bolt with a slotted brass head, coated with green baked paint on the hexagonal head. When using a Green Bolt, it is common to incorporate flat washers and S washers to improve the tightening condition, which requires separate inventory management and assembly work for the washers. ↓ 【After】 ■Washer-integrated Green Bolt By adopting a type of Green Bolt that incorporates flat washers and S washers into the screw, the assembly work for the washers becomes unnecessary. Furthermore, by using flat washers and S washers, the tightening torque can be equalized, eliminating bolt loosening. *For more details, please refer to the catalog or feel free to contact us.

Metal Tapping Screws and Bolts "Altrax(R)"

Ensure axial force equal to or greater than that of small screws and bolts! Tapping screws for lightweight alloys.

"Altrax(R)" is a tapping screw for lightweight alloys such as aluminum and magnesium. It has a very high axial force, providing a fastening strength equivalent to or greater than that of bolts (machine screws). There is also minimal reduction in fastening strength due to environmental changes. Regular tapping screws are subjected to carburizing hardening, which raises concerns about brittle fracture; however, this product undergoes quenching and tempering, significantly reducing the risk of brittle fracture. 【Features】 ■ Easy screwing in due to a special tip shape (close to triangular) ■ The 33° thread angle results in a smaller volume for forming the female thread, leading to lower screwing torque ■ An ideally balanced thread profile in relation to the strength of lightweight alloys ■ The cross-section of the screw is perfectly round ■ A large contact area with the mating material allows for stable long-term fastening *For data and material requests, please feel free to contact us through the Yamashina website: http://www.yamashina.ne.jp/
