Special mountain shapes and valley shapes! Significant effects are achieved through the fastening of hard resins like fiber-reinforced plastics.
The "EVO PT" is a tapping screw for resin that features three small screw threads that serve as guides during insertion, preventing diagonal entry during screwing. The first thread at the tip has a larger diameter, which leads to the formation of the female thread, while the subsequent standard threads are inserted along the formed female thread, allowing for low screwing torque without being affected by the fitting length. We also offer a service tool called "EVO CALC" that allows for simulations of screwing torque, breaking torque, and axial force under the combination conditions you wish to fasten with this product. 【Features】 ■ Prevents resin cracking with low radial stress ■ Increases vertical axial force ■ Achieves fastening without the need for insert nuts ■ Realizes lower screwing torque compared to conventional products ■ Ensures smooth fastening without diagonal entry *For more details, please refer to the PDF document or feel free to contact us.

basic information
**Effects Brought by Each Characteristic (Excerpt)** ■ The 26° thread optimized for resin significantly reduces stress in the vertical direction while minimizing it in the radial direction between the screw and the resin. ■ It increases axial force in the vertical direction, alleviating concerns about radial cracking of the resin. ■ It demonstrates significant effects when fastening hard resins such as fiber-reinforced resin. ■ The three small thread peaks serve as a guide during insertion, preventing diagonal entry during screwing. *For more details, please refer to the PDF document or feel free to contact us.*
