[SSOO Nut Adoption Case] Solving issues of slippage and disengagement during high torque tightening! Introducing the speaker cover parts of a car door.

Attention those struggling with spinning or pulling out nuts embedded in resin! Introducing outsert nuts that protect resin components and allow for high torque tightening.

"Do you have any of these concerns?" - When tightening conventional insert nuts, they can spin or come loose... - I am looking for an insert nut that can be embedded after resin molding... - I want to reduce the number of screw parts for weight reduction... - Brass insert nuts are expensive due to material and processing costs... With the 'SSOO Nut', these concerns can be resolved. 【5 Features】 ● A shape that is resistant to spinning, preventing damage to resin products ● Can be heated instantly by high-frequency vibrations, allowing for post-embedding ● Excellent pull-out strength enables reduction in the number of screw parts and weight reduction ● Uses a widely distributed material (SWCH10R), eliminating worries about material cost fluctuations ● High-speed production through forging and rolling. Allows for cost-effective mass production compared to machining *For detailed information about the SSOO Nut that can solve your concerns, please view the catalog available for download or feel free to contact us.

Supports high-level torque tightening! Introducing case studies of SSOO. *Case studies are featured in the SSOO Technical Report available now.

Here is a case study of the adoption of high-torque compatible insert nuts (SSOO nuts). Adoption location: Speaker cover parts of a car door Target resin: PP-TD30 (Polypropylene Talc 30%) [Challenges before introduction] - We were looking for an insert nut that could withstand high torque tightening. [Deciding factors for introduction] - After conducting comparative tests with products from other companies, the SSOO nut was adopted because it demonstrated the highest strength. [Effects after introduction] - Since it can withstand high torque tightening, there is no occurrence of nut spinning or loosening. *For more details, please refer to the technical report digest available for download or contact us directly.

By reducing the number of screw components, we have achieved a weight reduction of approximately 17%! Here are examples of the adoption of SSOO nuts. *SSOO nut technical report available.

Here are some examples of adoption that contributed to weight reduction with the high pull-out strength of SSOO nuts. <Adoption Example 1> Adoption Location: Hydrogen discharge parts used in hydrogen fuel cell vehicles (4 SSOO nuts, M6 size, used per unit) Target Resin: PP-TD30 (Polypropylene Talc 30%) [Challenge] ■ To reduce the number of screw components for weight reduction (previously 6 per unit) [Solution] ■ High pull-out strength enabled the reduction of the number of components used [Effect] ■ Reduced the number of screw components to 4 per unit ■ Achieved a weight reduction of 8g (approximately 17%) for screws <Adoption Example 2> Adoption Location: Automotive filter components (2 SSOO nuts, M6 size, used) Target Resin: New material resin using plant-derived fibers (PP) [Challenge] ■ To reduce the number of screw components for weight reduction (previously 3) ■ Insufficient strength of the new material resin causes it to spin under the specified torque with conventional products [Solution] ■ High pull-out strength enabled the reduction of the number of components used ■ High torque resistance performance meets the specified torque requirements [Effect] ■ Reduced the number of screw components to 2 ■ Achieved a weight reduction of 4g (approximately 17%) for screws

Adopted for automotive intercooler parts and other resin components! Introducing examples of SSOO nut applications. *SSOO nut technical report available.

Here are some examples of cases where SSOO nuts were adopted due to their high torque resistance performance. <Adoption Case 1> Adoption Location: Automotive intercooler parts (3 SSOO nuts, M6 size used) Target Resin: PA66-GF35 (Polyamide 66, 35% glass fiber) [Challenges] ■ Need to tighten resin parts with high torque ■ Knurled type insert nuts slip when tightened too much [Solution] ■ Meets requirements with high torque resistance performance ■ No worries about slipping or coming loose [Effect] ■ Protects resin parts from damage <Adoption Case 2> Adoption Location: Turbo engine vehicle intercooler parts (2 SSOO nuts, M6 size used) Target Resin: PA-GF35 (66 nylon, 35% glass) [Challenges] ■ Requirement for tightening with high torque ■ Knurled type insert nuts experience slipping and coming loose [Solution] ■ Meets requirements with high torque resistance performance ■ No worries about slipping or coming loose [Effect] ■ Protects resin parts from damage *An intercooler is a component used to cool air compressed by a supercharger (such as a turbo or supercharger).

From "strong" to "cheap"? We achieved cost reduction for EV cars with a small nut. Let me share the secret!

"Cheaper" even a little. "Lighter" even a little. The SSOO nut has contributed to cost reduction for EV vehicles with its performance. ■ High torque compatible heat-pressed insert nut (outsert nut) 'SSOO Nut' Application: Electric component cases for EV vehicles Number used: 19 pieces per unit Initially set usage number during the development stage: 23 pieces per unit. With the strong fastening power of the SSOO nut, we reduced the number from 23 to 19 while ensuring sealing performance. ● Achieved cost reduction Cost reduction was realized by reducing the number of components. - Cost reduction due to the reduction in the number of nuts - Cost reduction due to the reduction in the number of bolts - Cost reduction due to the reduction in tightening work hours ● Achieved weight reduction → Also effective for improving fuel efficiency of EV vehicles - Weight reduction of 20g per unit just from the nuts - When combined with bolts, achieved more than double the "lightness" - Space reduction for fasteners allows for miniaturization of parts → Further weight reduction is possible The SSOO nut has achieved high pull-out strength and torque resistance. For more details on the "required pull-out strength" and "required free rotation torque" of this case, please feel free to contact us.
