All-stainless steel swivel eye bolt. Suitable for sites such as semiconductor manufacturing, nuclear power, and outdoors.
High strength, high corrosion-resistant duplex stainless steel
Rotate in the pulling direction while keeping the bolt fixed! Eliminates the hassle of adjustments! No special tools required.
Lateral loads on eye bolts are prohibited, but with a star point, even when the bolt is fixed, the ring part can rotate 360° in the load direction, eliminating the need to constantly align the ring surface with the pulling direction. This prevents potential accidents caused by the loosening of eye bolts due to neglecting the adjustment of the ring surface. Additionally, lateral hanging, which is prohibited with fixed tightened eye bolts, can be made possible while ensuring high safety.
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.

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.*
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.
The material is difficult to remove! It can be used for clamp fittings.
The tip of the bolt is characterized by a recessed shape. By using it with clamp fittings, it becomes less likely to come out when it reaches the counterpart material. Please feel free to contact us if you are looking for stable supply and high quality of mass-produced items. We can also accommodate original shapes for our customers.
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/
