Products Description
Our Twin End Screw, also known as Double-Ended Socket Screws or Hanger Bolts, are engineered for applications where two components must be connected with strength, precision, and the flexibility of disassembly. With both ends threaded-either identically or with custom thread types-these Two-Ended Screws are widely used in machinery, piping systems, mold structures, electronic assemblies, and construction frameworks.
From M6 Double-Ended Dowel Screws for wood-to-metal applications to high-strength custom studs for structural joints, we offer a comprehensive line of double-ended fasteners tailored for demanding mechanical use.

Unique Advantages
Exceptional Versatility Across Multiple Industries
Double Ended Socket Screws excel in a wide array of applications. In mechanical connections, they provide a secure and durable link between components. For pipeline installations, their design ensures a tight seal and stable connection, preventing leaks and ensuring the safe transport of fluids or gases.
Time - and Labor-Saving Installation
The dual-threaded design of M6 Double Ended Dowel Screws allows for quick and efficient installation. Unlike traditional fasteners that require separate nuts and washers, twin-end screws can be directly threaded into pre-tapped holes on both ends, saving time and reducing the number of components needed.
Excellent Load - Bearing Capacity and Stability
Hanger Bolts are engineered to provide strong and stable connections. The threads on both ends are designed to distribute the load evenly, ensuring a firm grip and minimizing the risk of loosening or failure under stress.
