DIN 985 Nylon Insert Hex Lock Nut

DIN 985 Nylon Insert Hex Lock Nut

Short Description:

DIN 985 is the technical standard for effective torque hex nuts with non-metallic inserts. The standard was developed by the Deutsches Institut für Normung (DIN), a German organization that develops technical standards for various industries. The DIN 985 standard specifies dimensions, materials and finishes for commonly used torque hex nuts with non-metallic inserts, ensuring compatibility and interchangeability between different manufacturers and suppliers. Positive torque hex nuts with non-metallic inserts are designed to provide locking against loosening and vibration. These nuts are hexagonal in shape with a washer-like non-metallic insert that creates a locking torque when the nut is tightened. The DIN 985 standard specifies the dimensions of hexagons, as well as of non-metallic inserts like washers. It also covers the materials used, including nylon, PTFE or other non-metallic materials. Good torque hex nuts with non-metallic inserts are used in a wide variety of industries including automotive, aerospace and machinery. They are designed to provide a safe and secure locking function, reducing the risk of loosening or loosening due to vibration or other external factors. The non-metallic insert also helps protect the mating surfaces from damage or scratches that can occur with metal nuts. In summary, DIN 985 is a widely recognized standard for common torque hex nuts with non-metallic inserts. Their standardized specifications and availability in a variety of sizes, materials and finishes make them a popular choice among manufacturers, suppliers and customers across industries requiring reliable threaded connection locking solutions.
