basic information
<Installation Procedure> 1. Pass the bolt through the fastening component. Ensure that the bolt has a thread accuracy of 6g (Grade 2) and that the tip of the threaded section has been chamfered. 2. Manually screw in the bolt until the friction ring makes contact with the tip of the threaded section. *Note: Screwing in from the friction ring side is not possible. 3. Tighten using a wrench or other fastening tools. 4. Confirm that the threaded section of the bolt extends more than two pitches from the friction ring. When removing, use a wrench or similar tool to unscrew until the friction ring is free from the bolt's threads. Once the friction ring is detached from the bolt's threads, you can unscrew it by hand. *For more details, please refer to the PDF document or feel free to contact us.
