A product lineup that realizes the "next strength" demanded by the times.
The necessity of high-strength bolts Size reduction due to increased strength → Lightweighting of fastening points contributing to improved fuel efficiency in automobiles Prevention of loosening due to increased fastening force → Improved fastening reliability Overcoming challenges related to high-strength bolts
A product lineup that realizes the "next strength" demanded by the times.
The tapping process for aluminum and zinc components can be eliminated, resulting in cost reduction.
A bolt that excels in preventing screw seizure and galling caused by diagonal tightening of bolts and nuts!
The "Access Point" is a bolt that has received high praise for its exceptional ability to prevent thread seizing and galling caused by diagonal tightening of bolts and nuts. The guide thread at the tip of the screw prevents biting caused by the tilt and pitch misalignment of the bolt and nut, improving the workability of the fastening process. 【Features】 ■ Ideal for preventing thread seizing and galling due to diagonal tightening of bolts and nuts ■ Improved workability of fastening ■ Prevents galling *For more details, please refer to the catalog or feel free to contact us.
Lightweight bolts made from aluminum, which has a specific gravity of one-third that of iron!
Aluminum bolts do not experience galvanic corrosion against aluminum, and since their specific gravity is 1/3 compared to steel, they are highly effective for weight reduction. The material specification is from the 7000 series, with a strength of 4T, and by applying anodizing treatment, high corrosion resistance and decorative qualities (various color variations) can be achieved. 【Features】 ■ No galvanic corrosion against aluminum ■ Significant weight reduction effect ■ High corrosion resistance and decorative qualities can be achieved through anodizing treatment *For more details, please refer to the catalog or feel free to contact us.
Bolts made of pure titanium and alloy titanium, specifically designed for lightweight construction.
This product uses pure titanium and alloy titanium to supply racing bolts and racing parts. It has high corrosion resistance and is lightweight. Please use it for fastening parts where weight reduction is required, such as racing components. 【Features】 ■Specialized for weight reduction ■High corrosion resistance *For more details, please refer to the catalog or feel free to contact us.
A multifunctional screw ideal for fastening parts that require grounding.
The "Earth Bolt" is a multifunctional screw that has a coating removal function at the tip and an earthing function in the threaded section. It features a locking section in the threaded part that provides two functions: electrical conductivity (earthing) with the female thread and resistance to loosening, while also reducing the screwing torque and improving workability. Please use it for fastening areas that require earthing. 【Features】 ■ Multifunctional screw ■ Ensures stable earthing function *For more details, please refer to the catalog or feel free to contact us.
Suppress loosening due to thermal expansion differences and prevent galvanic corrosion! Weight reduction and color coding based on usage locations are also possible!
The "Robutite P type" is a tapping screw for resin. The screw thread is set at a 45° angle to prevent resin cracking, and multiple concave shapes are provided on the outer circumference of the screw thread to enhance the loosening function. Due to the special thread angle and shape, it can be applied not only to resin but also to steel plates. 【Features】 ■ Special thread angle and shape ■ Applicable to both resin and steel plates ■ Enhanced loosening function *For more details, please refer to the catalog or feel free to contact us.
We will manufacture adapters that convert the pole diameter and shape of various existing columns in a short delivery time. Custom production is possible to meet site conditions and needs!
The "Pole Adapter" is an adapter that allows for the connection of poles with different diameters and shapes, such as round and square poles. It can be custom-made to meet specific needs, and surface treatments can be customized to suit the site environment and requirements, including raw finish, rust prevention, baked paint, and hot-dip galvanized finishes! 【Features】 ■ Capable of manufacturing pole adapters that convert existing poles or change diameters and shapes ■ Surface treatments: raw (no finish), rust prevention, baked paint, hot-dip galvanized finishes, etc. ■ Customized products tailored to the site environment and needs *Please refer to the PDF data of the "Pole Adapter" catalog available for download.
A screw-type plug bolt that allows for easy attachment and detachment and can be reworked.
The "AS type" is a screw-in plug bolt that allows for easy attachment and detachment of bolts and can be reworked. It features reliable bolt tightening and excellent corrosion resistance. It is suitable for mounting control panels, washbasins, bulletin boards, and more.

Compatible with anchor bolt diameters M12 to M80! Base plate oversized hole filling material.
The Parent-Child Filler Q type is the only type among parent-child fillers that can transmit shear force to anchor bolts in primary and secondary designs. To achieve this, a dedicated grout material called OF-Q grout is used in addition to the steel parent and child fillers. Furthermore, the shear force that can be transmitted is 70% of the allowable shear strength of the anchor bolts used; if this is exceeded, the size or number of anchor bolts must be increased to accommodate it. The applicable anchor bolts range from M12 to M80, and steel types with a tensile strength of 490 N/mm² or less can be used. There are specific conditions unique to the Parent-Child Filler Q, so for design, please refer to the "Q Type Design and Construction Standard Drawings" and the "Design Manual," and for construction, please refer to the various "Construction Manuals." *For more details, please refer to the PDF materials or feel free to contact us.
Install a split-type band on the existing closure joint and secure it with a centering bolt.
Install a split-type band on the existing closure joint and secure it with a centering bolt. By using it mainly on existing closure joints for the upper part of the water pipe bridge, the amount of expansion absorption of the joint is doubled, fulfilling its role as a seismic isolation joint. *For more details, please download the PDF or feel free to contact us.
