Description and Translation of GB/T 6182 Fasteners
GB/T 6182 fasteners, a key Chinese standard for mechanical components, function as high-strength hexagon slotted nuts widely used in automotive, machinery, and engineering equipment. Their primary role is to provide secure locking connections with bolts, transmitting clamping forces while preventing loosening under vibration and dynamic loads. These nuts feature a slotted design that allows insertion of cotter pins, ensuring reliable fastening in critical applications requiring anti-loosening performance.
In terms of materials, GB/T 6182 fasteners are predominantly manufactured from alloy steel (e.g., 8 级 and 10 级 per GB/T 3098.2) and high-quality carbon steel, offering excellent tensile strength and mechanical durability. For corrosion-resistant requirements, stainless steel variants (e.g., 304, 316) compliant with relevant standards are specified to ensure performance in humid or chemically exposed environments.
Surface treatments include zinc plating with passivation for enhanced rust resistance, phosphating to improve lubrication during assembly, and black oxide coating for increased wear resistance. These treatments effectively extend service life and optimize compatibility with various operating conditions.
Key characteristics of GB/T 6182 fasteners include standardized metric threads, hexagonal profiles with axial slots, and precise dimensional tolerances ensuring interchangeability. Their mechanical attributes feature specified proof loads (minimum 600 MPa for 8 级), appropriate hardness, and uniform thread geometry. Additionally, they exhibit reliable anti-loosening performance when paired with cotter pins and compatible bolts, making them indispensable in high-reliability mechanical assemblies and industrial applications.
