Knurled riveting nuts are precision fasteners made of high-quality low-carbon steel, medium-carbon steel, alloy steel, 304 stainless steel, 316 stainless steel, brass, aluminum alloy, and other materials. They belong to the secondary category of riveting parts under the primary category. They have a cylindrical structure with external knurled patterns in the center and metric machine threads in the inner hole. Common sizes range from M2 to M6. Surface treatments are diverse, including environmentally friendly blue-white zinc plating, color zinc plating, black zinc plating, environmentally friendly nickel plating, zinc-nickel alloy plating, Dacromet coating, electrophoresis, PVD, stainless steel natural finish, and stainless steel passivation. In terms of strength grades, carbon steel can reach 4.8, 6.8, and 8.8; stainless steel has A2-50, A2-70, A4-70, and A4-80; and non-ferrous metals are no lower than 4.8. This product is suitable for riveting and fixing sheet metal parts, assembling automotive parts, installing electronic equipment housings, connecting home appliances, assembling communication equipment, and other scenarios. Common aliases include knurled rivet nuts, external toothed riveting nuts, and galvanized knurled nuts.
We support customized production based on customer-provided drawings or industry standards.
