Released the bolt anti-rotation washer "Tsure Zero Washer."
Nippon Pralado Co., Ltd. has released the "Tsure Zero Washer," a washer designed to prevent the rotation of bolts with diameters ranging from M12 to M72. ■ Features of the Anti-Rotation Washer "Tsure Zero Washer" 1. A washer that prevents bolt rotation Unlike washers that utilize surface irregularities from knurled processing to create friction resistance, the anti-rotation Tsure Zero Washer has a special structure that changes the equivalent friction diameter. It is currently under international patent application. The conical shape on the back and the hexagonal design increase the effective friction diameter against the seating surface, resulting in the reaction torque from the bolt head being more than twice as large as the tightening torque of the nut. This prevents the washer from rotating and stops the bolt head from rotating together. As the tightening torque of the nut increases, the reaction torque from the bolt head also increases, ensuring that the bolt does not rotate until the tightening is complete. 2. Significant reduction in bolt tightening and loosening time, manageable by one person By simply replacing standard flat washers with the Tsure Zero Washer, there is no need for cumbersome anti-rotation tools or backup wrenches, leading to a substantial reduction in the time required for bolt tightening operations.
A nut that does not loosen even after 1 million vibration tests (3D vertical and horizontal)! Compatible bolt sizes: M14 to M100.

A nut that can tighten a large bolt with "1/100 of a small torque."

The tension nut won the 36th "Small and Medium Enterprises Excellent New Technology and New Product Award."
The "36th Small and Medium Enterprises Excellent New Technology and New Product Award," hosted by the Resona Small and Medium Enterprises Promotion Foundation and the Nikkan Kogyo Shimbun, has awarded a Encouragement Prize to Japan Plarad's "Tension Nut." About the Tension Nut: For large bolts ranging from M30 to M100, the tightening torque can reach several thousand to tens of thousands of Nm, requiring large hydraulic tools or electric tools. However, the Tension Nut allows for easy tightening of large bolts using only a hand torque wrench by tightening the Hertz screw without the need for electricity or air. The special structure of the Tension Nut, with its "slope disc," generates higher axial force as it resists the reverse rotation that would loosen the bolt, making it a nut that does not loosen. About the Small and Medium Enterprises Excellent New Technology and New Product Award: The Resona Small and Medium Enterprises Promotion Foundation, in collaboration with the Nikkan Kogyo Shimbun, conducts awards for excellent new technologies and new products with the aim of promoting the technology of small and medium enterprises and contributing to the development of Japanese industry. Awards are given for outstanding new technologies and products, including the Minister of Small and Medium Enterprises Agency Award (General Category), the Chairman of the Organization for Small & Medium Enterprises and Regional Innovation Award (Software Category), Excellent Award, Good Award, and Encouragement Award.
