Double-headed bolts are designed to address potential thread wear and damage that can occur with frequent disassembly. This innovative design ensures the connection remains reliable and stable over time. Additionally, to prevent loosening under external loads, effective anti-loosening measures are implemented, providing secure and firm connections. As a leading China supplier and factory for double-headed bolts, we prioritize quality and durability, making our products an excellent choice for your fastening needs.
1. Connecting Mechanical Components
Used to connect mining machinery, bridges, automobiles, motorcycles, boiler steel structures, suspension towers, and large-span buildings.
2. Installation Accessories
Ideal for observation mirrors, mechanical seal seats, and reduction frames. One end screws into the body, allowing frequent disassembly without damaging the main structure.
3. Thick Plates & Limited Space
The best choice for thick connectors or areas where hexagonal bolts won't fit, such as concrete roof trusses and monorail beam suspensions.
4. Fixed Connecting Rod
Commonly used for mechanical fixed rods, featuring threads at both ends with variable middle screw thickness based on usage requirements.
Frequently Asked Questions
QWhat is a double headed bolt and how does it differ from a standard bolt?
A double headed bolt (stud bolt) has threads at both ends. Unlike standard bolts with a head, these are screwed into a tapped hole on one side and secured with a nut on the other, perfect for frequent disassembly.
QWhat thread sizes are available for double headed bolts?
They are available in metric sizes including M6, M8, M10, M12, M14, M16, M18, M20, M22, M24, M27, M30, and M33 for various industrial applications.
QWhat industries commonly use double headed bolts?
They are widely used in mining, bridge construction, automotive manufacturing, steel structures fabrication, and large-scale building construction.
QWhat does the designation "D-HDZ" indicate?
"D-HDZ" indicates Hot-Dip Galvanized coating for M10 sizes and above, providing superior corrosion resistance for outdoor or harsh environments.
QWhy are double headed bolts preferred for thick plate connections?
They offer a practical solution where standard bolts cannot be conveniently inserted or turned, specifically in concrete trusses and limited-access suspensions.
QCan double headed bolts be reused after disassembly?
Yes. One end stays threaded in the base while only the nut is removed, which minimizes wear on the main structure and extends the fastener's service life.
