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

第一工業 第一工業 鋲螺事業部(ネジ・ボルト・ナット等締結部品 製造販売. 静岡県浜松市)
[SSOO Nut Case Study] Introducing a speaker cover component for automobiles that resolves issues of slippage and detachment during high torque tightening. [Challenges] When using conventional square nuts or knurled nuts: - The nut slips when tightened with high torque. - The nut can detach due to impact, damaging the resin. [Solution] By using our original product, the 'SSOO Nut': - There is no worry of slippage during high torque tightening. - It is designed to be difficult to detach from the resin, preventing damage. The SSOO Nut features a special octagonal groove into which the resin fits after being embedded in the plastic, providing resistance to rotation even under high torque. Additionally, the shaft has fine irregularities, improving detachment strength compared to conventional products. As a result, high torque tightening can be achieved while protecting resin components. The SSOO Nut is also used in a wide range of applications, including automotive intercooler components, filter components, and system components for hydrogen fuel cell vehicles. If you are interested in the SSOO Nut, please contact us or refer to the related catalog.

[SSOO Nut Adoption Case] Speaker cover parts of the car door section

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.

What is the nut that made cost reduction for EVs a reality?! 【Case Study Introduction】

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.

[New Lineup] Indoor doors that create a "noiseless space" by eliminating lines and steps.

  • NEW
  • PRODUCT

In recent years, while the size of residential spaces has been shrinking, there has been a growing demand from architects and designers for designs that "reduce lines as much as possible." However, designing spaces to appear clean and spacious by making door heights reach the ceiling or by minimizing the visibility of frames has posed challenges that require high skill levels from carpenters and significant construction time when attempted with conventional on-site construction methods. Against this backdrop, this year's Dretas has developed doors and storage fixtures that do not reveal frames, with the concept of "creating a noise-free space with empty space." ■ Base Frame (Fixtures) The structure hides the frame within the wall, achieving a refined design without the frame being visible from either side. It features a specially designed frame and concealed hinges that allow for 180-degree opening and closing. Frame widths (132mm, 147mm, 183mm) are set to accommodate wall thickness, eliminating the need for frame processing and supporting smooth installation. ■ Outset Frame (Storage Fixtures) The structure has the frame attached to the inside of the door, allowing the door and wall to fit flatly together. It can be configured for two or three panels, seamlessly blending even large wall storage into the space as if it were "just a wall." By using additional elements like the 3mm thick "Baseboard S-type," the installation becomes even more beautiful, enhancing the noise-free space.
