Railroad Lag Screw
A railroad lag screw is a specialized type of fastener used in railway construction and maintenance. It features a threaded shaft with a pointed tip, allowing it to be directly inserted into wooden or concrete sleepers (ties) that form the foundation of railway tracks. Railroad lag screws are designed to securely fasten rail components to the sleepers, providing stability and support to the track structure.
These screws are commonly used in conjunction with other fasteners such as spikes or bolts to ensure the integrity and safety of railway tracks. They are known for their durability and ability to withstand the heavy loads and stresses associated with railway operations.
GNEE RAILWAY Rail specializes in producing high-quality railroad lag screws, along with a comprehensive range of railway sleeper screws and track spikes, all manufactured to meet international standards. If you have any specific requirements or inquiries regarding railroad lag screws or other railway fastening products, please feel free to contact GNEE RAILWAY Rail for assistance.
