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.
