Product Introduction
A railway flat washer is a fastening component used within a railway track fastening system, designed to function in conjunction with corresponding bolts, nuts, and other fastening elements. Within a railway fastening assembly, a flat washer is typically installed at the bolted connection point; it provides a load-bearing contact surface, improves the interface conditions between the fastener and adjacent components, and—depending on the specific structural design—helps distribute localized contact pressure.
The structure, dimensions, thickness, material, and surface treatment of a railway flat washer must be determined based on the specific type of railway fastening system, the relevant design drawings, and applicable technical standards. As flat washers may vary depending on the specific model of the railway fastening system, the selection of the product should be based on the actual technical requirements.
Product Function
- Distributing Compressive Stress: By increasing the load-bearing contact area between the nut and the connected component, it prevents excessive localized pressure during tightening, thereby protecting the surfaces of base materials—such as backing plates or gauge-retaining clips—from being crushed or indented.
- Protecting Contact Surfaces: It acts as an interface between the nut and the workpiece during the tightening process, reducing surface damage (such as scratching or scoring) caused by rotational friction.
- Ensuring Uniform Force Transmission: Under the repetitive impact of dynamic loads from trains, it helps distribute the bolt’s preload evenly, supports the maintenance of the fastening system’s preload state, and lowers the risk of stress concentration.
Our company supplies railway flat washers that meet national standards. We also offer OEM and ODM customization services, developing washers to specific requirements based on customer drawings or international standards. These products are suitable for conventional railways, high-speed railways, and overseas rail projects. We can provide them as part of a complete fastening system, alongside rail clips, screw spikes, nuts, and gauge blocks.
