The prevailing torque type hexagon nut with a non-metallic insert, manufactured in accordance with DIN 985 standards, is designed for reliable 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 and humidity are minimal. The hexagon shape allows for easy installation and removal using standard tools, while the right-hand thread direction ensures compatibility with a wide range of metric fine-threaded bolts and screws. These nuts are engineered to maintain a secure grip under vibration and dynamic loads, thanks to their non-metallic insert, which increases friction and prevents loosening. This feature is particularly beneficial in applications where movement or vibration is prevalent, such as in automotive, machinery, and structural assemblies. The nuts comply with ISO 10512 and NF E25-412 standards, ensuring that they meet rigorous quality and performance benchmarks required in industrial settings. Ideal for use in various sectors including automotive, construction, and machinery manufacturing, these hexagon nuts are compatible with standard nuts, washers, and inserts, providing versatility in assembly. Their robust design and adherence to industry standards make them a reliable choice for engineers and maintenance professionals seeking durable fastening solutions.
