Stepped rivets are precision fasteners with a unique double-step cylindrical shank structure. They feature a rounded head and a flat end. This stepped structure enables precise connection and positioning of plates or components of varying thicknesses, making them widely used in mechanical equipment component connections, mold assembly and fixing, automated equipment positioning, hardware anti-loosening and fixing, and furniture panel connections. The products are available in various materials, including carbon steel and stainless steel, and can undergo surface treatments such as blackening, phosphating, nickel plating, and zinc plating to meet the needs of different environments. Their strength grades vary depending on the material, ranging from 4.8 to 8.8 for carbon steel, A2-50 to A4-80 for stainless steel, and no less than 4.8 for non-ferrous metals.
We support customized production based on customer-provided drawings or industry standards.
Available grades: Carbon steel 4.8/6.8/8.8/10.9/12.9; Stainless steel A2-50, A2-70, A4-70, A4-80
