The prevailing torque type hexagon nut with a non-metallic insert, compliant with DIN 985 standards, is engineered for secure fastening in various industrial applications. Constructed from hardened carbon steel, these nuts are zinc plated to provide basic indoor corrosion protection, making them suitable for environments where moisture exposure is limited. The non-metallic insert enhances the nut's locking capability, ensuring that it maintains its grip under vibration and dynamic loads, which is critical in applications such as automotive assembly and machinery maintenance. These nuts feature a hexagon head design, allowing for easy installation and removal using standard tools. They are available with metric fine threads, ensuring compatibility with a wide range of bolts and screws, and are designed for right-hand thread direction, which is the most commonly used configuration in industrial settings. The product adheres to ISO 10512 and NF E25-412 standards, ensuring reliability and consistency in performance. Ideal for use in sectors such as construction, automotive, and machinery, these hexagon nuts are versatile components that can be paired with compatible standard nuts, washers, or inserts to create secure assemblies. Their robust construction and locking mechanism make them suitable for applications that require a dependable fastening solution, particularly in environments subject to vibration or movement.
