Double end Studs are threaded at both ends, with a light rod in the center, and are commonly used for parts that require two-way fastening or frequent disassembly. In pipeline flanges, high-pressure vessels (such as reactors, heat exchangers) to achieve precise alignment of the sealing surface, through the two ends of the nut to adjust the preload. Used in machinery manufacturing for assembly of heavy equipment such as bearing housings, gearboxes, etc., to facilitate unilateral disassembly during maintenance. Connecting thick plate members in steel structure bridges or buildings, the middle light bar can reduce stress concentration and improve vibration resistance. When fixing automobile engine block and bracket, the double-head design is suitable for high temperature environment, and the surface is galvanized or Dacromet treated to enhance the anti-corrosion performance, which is a flexible and efficient long-lasting connector in industrial assembly. |
