The prevailing torque type hexagon nut with a non-metallic insert, compliant with DIN 985 standards, is constructed from hardened carbon steel and features a zinc-plated yellow passivated surface treatment. This treatment provides basic indoor corrosion protection, making it suitable for use in environments where moisture exposure is limited. The nuts are designed with a right-hand thread and metric thread specifications, ensuring compatibility with standard bolts and screws commonly used in industrial applications. Engineered for reliable fastening, these nuts incorporate a non-metallic insert that enhances their locking capability, preventing loosening under vibration and dynamic loads. This feature is particularly beneficial in applications where maintaining torque is critical, such as in automotive, machinery, and structural assemblies. The hexagon head design allows for easy installation and removal using standard tools, facilitating efficient maintenance and assembly processes. These nuts meet various industry standards, including ISO 10511 and NF E25-412, ensuring consistent quality and performance across different applications. They are suitable for use in a wide range of sectors, including construction, automotive, and manufacturing, where robust fastening solutions are required. The prevailing torque design, combined with the durable material properties, makes these nuts an essential component for engineers and maintenance professionals seeking dependable fastening solutions in their projects.
