Hexagonal head blind hole rivet nuts are precision fasteners with an external hexagonal head and a cylindrical shank. Their internal threads use standard metric mechanical threads, and the tail is designed as a blind hole to effectively prevent moisture, dust, and other impurities from entering, improving the sealing and reliability of the connection. This product has a compact structure, is easy to install, and is suitable for connecting and fixing various thin plates and sheet metal parts. Common sizes range from M3 to M10. Various high-quality materials such as 304 stainless steel, 316 stainless steel, low carbon steel, and medium carbon steel can be selected to meet different needs. A variety of surface treatments are available, including stainless steel natural finish, passivation, environmentally friendly blue-white zinc, color zinc, and Dacromet, to meet the requirements of different operating environments. They are widely used in the assembly of sheet metal chassis and cabinets, electronic equipment housings, automotive sheet metal parts, communication equipment, and medical device sheet metal parts.
