Suppresses deformation of resin products. Special shape that is less likely to slip even under high torque. High pull-out strength also reduces the number of screw components and contributes to weight reduction.

The "SSOO Nut" features fine irregularities on the surface of the shaft to enhance torque resistance performance. It is a heat-pressed insert nut that achieves "difficulty in rotation" and "high pull-out strength." Even when tightened with high torque, it does not slip, preventing damage to resin products. Additionally, its excellent pull-out strength contributes to weight reduction by reducing the number of components. Available sizes include M4, M5, M6, and M8. 【Features】 ■ Shape designed to prevent slipping and rotation, protecting resin products from damage ■ Contributes to weight reduction through the reduction of components and downsizing ■ Torque strength and pull-out strength have been verified through testing ■ Proven track record as an automotive component *You can download PDF materials such as verification test data. For more details on specifications and pilot holes, please feel free to contact us.

By using SSOO nuts, the cost of bolts and nuts is reduced to 2/3! We are offering a free case study that demonstrates achieving a 2/3 cost reduction and a 17% decrease in threaded parts!

This is an introduction to a case where the automotive parts that typically used six insert nuts were replaced with the "high-strength" SSOO nuts from Daiichi Kogyo (high torque compatible insert nuts), resulting in a reduction of the number of components to four. By reducing the number of insert nuts by "two," the number of bolts was also decreased, leading to a cost reduction of about two-thirds and a weight reduction of 17% for the threaded components. ■ We are currently offering free case study materials that demonstrate the effects of cost reduction and weight reduction! ■ *For more details, please view the PDF available for download.

This is a strong insert nut that prevents slippage (co-rotation and idling) caused by bolt tightening and protects resin products from damage.

Insert nuts for resin (plastic) have traditionally utilized knurled, square, and hexagonal shapes, which have raised concerns about the nuts deforming the resin and spinning freely (slipping or idling) when bolts are tightened with high torque. As a result, we received strong requests from customers to develop insert nuts with shapes that can withstand high torque (high torque strength). We conducted research, development, and prototyping in-house and devised an original shape of insert nut that can handle high torque. It is designed for use during resin molding and also boasts excellent tensile strength (pull-out strength). 【Features】 - Strong nuts that prevent spinning (slipping or idling) and protect resin products from damage. - A unique octagonal shape that enables "high torque tightening," which has not been available before. - We have realized a shape that is difficult to spin, as requested by many customers.

We are offering free technical materials that demonstrate the strength of SSOI nuts! The materials include a wealth of test data such as tensile tests, torque strength tests, and tightening tests.

The SSOI nut improves torque resistance performance by being molded into a special octagonal shape. It is an insert nut that achieves "difficulty in rotation" and "difficulty in removal," molded simultaneously during resin molding. This technical report presents abundant test data, including tensile tests and torque strength tests, as well as adoption results, explaining the excellent performance of the SSOI nut. ● "Difficulty in rotation" By molding into a special octagonal shape, the torque resistance performance has been significantly improved compared to conventional insert nuts. It prevents the nut from spinning freely (back spinning) during high-torque tightening. 【Verification Test Results】 Torque strength test results (Material: MC Nylon): 25N·m or more ● "Difficulty in removal" Designed for simultaneous use with resin molding, it has excellent tensile (pull-out) strength. It features high vibration resistance and high rotational torque, making it difficult to loosen. 【Verification Test Results】 Pull-out load test results (Material: MC Nylon): 8250N ● Shape As a non-through type, there is no need to worry about resin flowing into the screw hole. 【Adoption Examples】 Resin parts such as air cleaners and intake manifolds. *For detailed technical information, please refer to the download.

Through research and development, we are striving to improve the safety, performance, and quality of our screw products!

Mechanical structures such as automobiles, home appliances, and buildings are assembled by joining multiple parts together. Therefore, joining is common across all industries and is the most fundamental technology for maintaining performance and quality. Joining can be broadly classified into welding through the melting and solidification of metals, chemical adhesion, and mechanical fastening through screws. Each of these methods has many advantages and is an important joining technique, but the only method that allows for high strength and the possibility of disassembly and reuse is mechanical fastening with screws, which is also considered to play an important role in today's environmental issues. Screws are a representative mechanical component that was standardized by ISO early on as a key element of globalization and are widely distributed in the market; however, there are significant differences in safety, performance, and quality among manufacturers. Through diligent research activities to meet users' needs for screw fastening, we are committed to improving the safety, performance, and quality of screw products.
