Hexagon Flange Bolt
Hexagonal flange bolts are precision fasteners with an external hexagonal head and a flanged structure. The flange face features anti-slip serrations, effectively enhancing friction and stability during tightening. The shank uses a full-thread metric machine thread design, and the tail is flat. Common sizes range from M3 to M20. These bolts are available in a wide variety of materials, including 304 stainless steel, 316 stainless steel, low-carbon steel, medium-carbon steel, and alloy steel, allowing for selection of appropriate materials based on different application scenarios. Various surface treatments are available, including stainless steel natural finish, stainless steel passivation, environmentally friendly blue-white zinc plating, color zinc plating, hot-dip galvanizing, and Dacromet coating, meeting corrosion protection requirements in different environments. Their structural features make them widely applicable in various scenarios such as mechanical equipment assembly, automotive parts connection, rail transit equipment, outdoor engineering structures, and sheet metal fastening.
