We offer a wide range of sizes! Introducing thick hexagon socket bolts with strength classification 12.9.
We recommend the "Large Diameter Hexagon Socket Bolt Strength Class 12.9" for molds and industrial machinery. Traditionally, for domestically produced large diameter hexagon socket bolts exceeding M20, those of strength class 10.9 were available in the market. Therefore, when bolts of strength class 12.9 were absolutely necessary, we had to resort to custom manufacturing, which increased costs. However, thanks to the Taiwanese screw manufacturer YFS, we can now maintain a constant stock of hexagon socket bolts of strength class 12.9 with nominal diameters M22, M24, and M30 in Japan, greatly improving availability. We encourage you to consider this option. 【Product Lineup】 ■M22 ■M24 ■M30 *For more details, please refer to the PDF document or feel free to contact us.
Boasting a tensile strength of 1,400 N/mm² while achieving over 9% elongation!
A jointly developed product with the top-tier manufacturer, Kyokuto Seisakusho Co., Ltd., known for its high technical capabilities. A hexagon socket bolt boasting an ultra-high strength of "14.9". Utilizing high-strength steel with excellent "delayed fracture characteristics," it achieves a tensile strength of 1,400 N/mm² while maintaining an elongation of over 9%. The adoption of aerospace-grade "MJ screws" enhances fatigue resistance. "Ultra strength" resolves issues in maintenance. *For more details, please contact us or download the PDF.*
Adopting a duplex stainless steel that combines excellent corrosion resistance and outstanding strength, achieving a strength class of 12.9 while being stainless!
Our product, boasting unparalleled strength, high ductility, and excellent corrosion resistance, is an ideal choice for demanding applications.
It is also suitable for areas without clearance or where you do not want to use cross holes for design reasons.
The "NS-LOW HEAD Power8" is a high-strength hexagon socket bolt with an extremely low head shape that significantly exceeds the conventional strength grades of 4.8/5.8, achieving a strength grade equivalent to 8.8. It offers substantial weight reduction compared to JIS standard products. It is also suitable for areas where there is no clearance or where a cross hole is not desired for design reasons. 【Features】 ■ Achieves a strength grade equivalent to 8.8 with an extremely low head shape ■ Substantial weight reduction compared to JIS standard products ■ Ideal for areas without clearance or where a cross hole is not desired for design reasons *For more details, please refer to the PDF document or feel free to contact us.
High intensity and lightweight are possible! It keeps the head low and achieves space-saving.
The "A2-100" is a low-head hexagon socket bolt made from high-strength stainless steel (SUS304CUN). While improving strength, which is important when considering compactness and lightweight design, the head is kept low to achieve space-saving. It is common for stainless steel low-head bolts to have no strength guarantee equivalent to A2-50, but this product guarantees a tensile strength of 1,000 N/mm². 【Features】 ■ High strength and lightweight design possible ■ Low head design achieves space-saving ■ Can replace SCM products ■ Strength guarantee *For more details, please refer to the PDF document or feel free to contact us.

We also have the UNBRAKO hex socket bolts, which have the highest strength and precision among commercially available products, in stock according to the Unified standard!
UNBRAKO hex socket bolts possess the highest levels of strength and fatigue resistance available in commercial products. We also have a stock of Unified sizes ready for immediate delivery. Please feel free to contact us.
This is a new high-strength fastening solution developed through collaboration with top manufacturers boasting advanced technology in Japan.
By adopting high-strength bolt steel with excellent "delayed fracture resistance characteristics," we achieve a tensile strength of 1,400 N/mm² while maintaining an elongation of over 9%. Furthermore, the use of aerospace-grade "MJ screws" results in a shallower valley at the screw section and a larger radius at the bottom of the valley compared to standard specifications, which enhances fatigue resistance by alleviating the notch effect.
