basic information
1. Tightening effect due to the spring's compressive force and pressure By attaching it to the bolt, the nut surface is pressed by the three sides of the spring, demonstrating a tightening effect. 2. Visual confirmation of completion Due to the tension, the triangular outer diameter deforms into a hexagon. When the end of the nut contacts the nut and expands, and it becomes parallel to the nut, the installation is complete. 3. Can be installed on existing bolts and nuts If the remaining length of the bolt is five turns or more, installation is possible. In the case of new installations, it can be inserted in the order of the 12-point socket, petal fastener, and nut for integrated installation. *For more details, please download the PDF or feel free to contact us.*
