No special tools are required for tightening; a wrench or similar tool will suffice! Repeated use complies with JIS, ISO, etc.
This product is a nut that can exert a locking effect with just one piece. The structure involves pressing the conical part on the top of the nut at three points, which expands or compresses one or two threads of the nut inward. It does not come loose due to incomplete tightening or when the bolt is in an intermediate position, as it generates friction torque. Additionally, it is made of the same metallic material, which excels in heat and cold resistance. 【Features】 ■ Exerts a locking effect with just one piece ■ Made of the same metallic material, excelling in heat and cold resistance ■ Reusable in compliance with JIS, ISO, etc. ■ Tightening tools such as wrenches can be used; no special tools are required *For more details, please refer to the PDF materials or feel free to contact us.
