This is a thin head type of blind nut with a spline.
This is a blind nut with splines applied to the outer circumference of the nut body. The splines bite into the pilot hole, providing stable and high strength. It is effective for soft base materials such as aluminum.
A press nut that achieves high torque by sinking part of the body. It is a medium size ranging from M8 to M12.
This unique press nut with a custom design prevents the nut from rotating by press-fitting part of its hexagonal body into the base material. Additionally, it prevents the nut from coming loose due to metal flow. By using press-fitting for nuts ranging from M8 to M12, it achieves a strong bonding force comparable to that of welded nuts. There is no need for processes like spatter treatment or anti-corrosion treatment, and it can be press-fitted from either the punch side or the press side. It is used in components made of aluminum and in copper busbars for power supply.

This is an aluminum alloy nut for CFRP that prevents galvanic corrosion. It allows for fastening with metal bolts to CFRP without worrying about galvanic corrosion.
■ High Risk Mitigation for Galvanic Corrosion These are aluminum alloy nuts. They are treated with a patented special hard anodized coating on the surface to ensure electrical insulation and effectively prevent the occurrence of galvanic corrosion. When mounted on CFRTP containing 40% carbon fiber and subjected to corrosion resistance evaluation using the JIS saltwater alternating immersion method, they maintain corrosion resistance for 3,000 hours. ■ Synergy in Weight Reduction The specific gravity of aluminum armor nuts is one-third that of iron. This allows for weight reduction of both the material using CFRP and the nuts themselves simultaneously. ■ Strong Fastening Capability The pull-out strength exceeds that of conventional knurled insert nuts when mounted on CFRTP and pulled out. Additionally, the resistance to rotation and the strength of the internal threads are at the level where a bolt of strength class 10.9 would break when screwed in. The secret lies in the shape of the nut, which allows for easy flow of carbon fiber. ■ Contribution to Overall Cost Reduction The costs associated with galvanic corrosion measures that were previously necessary are reduced. This lowers the overall manufacturing costs, promotes the use of CFRP, and contributes to product weight reduction.
I will introduce a case study on the development of aluminum alloy insert nuts for CFRP that avoid the risk of galvanic corrosion.
