Special for resin! Torque of 31.0Nm, nut with a knurling ratio of 1.8 times.
Octa Lobular Series SSOO Nut SSOO Nut PLUS SSOI Nut SSOO Bolt
[Free Technical Materials Available] Are you having trouble with fastening resin? There are screws for resin that can be tightened with high torque.
Are you having trouble with fastening resin? When tightened with high torque, the resin can crack. It can spin, making it impossible to apply high torque, and the screw may come loose. We have a series of screws for resin that can solve these issues. Thanks to the special octagonal shape, the spinning torque is 1.8 times that of knurled products (31.0 Nm). The pull-out strength is 1.2 times greater (2713 N) (resin material: PP). This series of screws for resin allows for high torque tightening without damaging the resin. We offer both simultaneous molding and post-filling types, as well as nuts and bolts. Being made of steel, they are more cost-effective compared to brass materials. Not only is the material price itself low, but the ease of obtaining the material and compliance with RoHS directives are also not an issue. We have received numerous inquiries from customers facing difficulties with the availability and rising prices of brass materials. We also have technical documentation summarizing the results of verification tests on spinning torque and pull-out load. You can also download helpful technical materials that explain the basics of insert nuts.

Detailed information

This is a case of weight reduction achieved by adopting high-torque compatible press-fit insert nuts, specifically SSOO nuts. By changing the insert nuts to SSOO nuts, we were able to reduce the number of nuts used from 6 per unit to 4 per unit due to their high pull-out strength. Similarly, bolts were also reduced, resulting in a total weight reduction of 17%.

Company information
Connecting things to things. We propose the optimal fastening solutions to meet our customers' needs. Behind this proposal capability lies our technical expertise to analyze and evaluate everything from materials to fasteners, our development and manufacturing capabilities to design and produce both bolts and nuts, and our procurement strength with partnerships with 200 cooperating manufacturers. Through the small component of screws, we contribute to the development of various industries. At Daiichi Kogyo, we manufacture both bolts and nuts. Although they are both "screws," the manufacturing processes, equipment, and materials for bolts and nuts are different. We possess the processing equipment and know-how for both. With 60 years of experience in screw manufacturing, as a specialized group that produces both bolts and nuts, we leverage our accumulated know-how to provide the bolts and nuts that our customers need.
