The Spiralock Hexagon Lock Nut with Flange, conforming to ISO 4161 standards, is engineered from hardened carbon steel and features a zinc-plated surface treatment, providing basic indoor corrosion protection. This product is designed to accommodate right-hand threads and is compatible with standard male fasteners, including those with thread tolerance classes of 4g6g, 6g, 6h, and MJ. The unique thread configuration of the Spiralock design enhances the nut's resistance to vibration loosening, effectively eliminating the need for additional locking devices. With its flange design, this lock nut improves joint fatigue life and facilitates consistent reusability, making it an efficient choice for various applications. The assembly process is streamlined, reducing overall assembly time and contributing to lower life cycle costs of threaded joints. It is important to note that the Spiralock design typically requires 10% to 20% greater torque than standard joints, as the assembly forces are redirected from an axial to a radial direction. This torque/tension relationship should be assessed in the context of the specific joint to determine the appropriate torque needed to achieve the desired tension. The Spiralock Hexagon Lock Nut is suitable for use in a range of industrial applications, including automotive, construction, and machinery assembly, where reliable fastening is critical. It meets relevant industry standards and certifications, ensuring compliance and performance in demanding environments.
