Galvanized double-headed bolts, blackened double-headed bolts 4.8.8.8 grade

The function of double headed bolts:

1. Connecting mechanical components: Double headed bolts have threads at both ends and a screw in the middle, commonly used to connect mechanical components such as mining machinery, bridges, automobiles, motorcycles, boiler steel structures, suspension towers, large-span steel structures, and large buildings.

2. Installation accessories: When large equipment requires the installation of accessories, such as observation mirrors, mechanical seal seats, reduction frames, etc., double headed bolts can play a role. One end is screwed into the main body, and after installing the accessories, the other end is equipped with a nut. Due to the fact that these attachments may require frequent disassembly, using double headed bolts for replacement would be very convenient.

3. Connecting thick plates and places where it is inconvenient to use hexagonal bolts: In cases where the thickness of the connectors is large or the connection area is not convenient to use hexagonal bolts, such as concrete roof trusses, roof beam suspensions, monorail beam suspensions, etc., double headed bolts are also a suitable choice.

4. Fixed connecting rod: Double headed bolts are also commonly used for mechanical fixed connecting rods, with corresponding threads at both ends. The thickness of the middle screw varies depending on actual usage.
