A railway spring washer is a specialized type of spring washer used in railway track fastening systems to help prevent loosening and maintain tension, particularly under vibration. It's a conical-shaped washer that applies a spring force and absorbs shock, crucial in preventing fasteners from loosening due to the constant vibrations of passing trains.
Helical spring lock washers have been historically among the most widely used anti-loosening assembly components on the market. They have been specified in thousands of assembly applications. Called split lock washers in the China they have developed on both continents.

Here's a more detailed explanation:
Function:
Spring washers, including railway spring washers, are designed to provide a spring force that helps maintain tension on fasteners, like nuts and bolts, even when subjected to vibrations.
Construction:
They are typically made from durable materials like carbon steel or inconel and can be designed with single or double coils, depending on the application.
Benefits:
- Prevents Loosening: The spring force helps counteract vibrations and prevents fasteners from loosening over time.
- Absorbs Shock: They can help absorb impact and vibrations, protecting the fastening system and the track structure.
- Maintains Preload: They help maintain an initial level of preload on the fasteners, ensuring a secure connection.
Railway Applications:
In railway applications, spring washers are commonly used with rail nuts and other fasteners, particularly on track installations where constant vibrations are a concern.
Types:
Besides railway spring washers, other types of spring washers, like Belleville washers, are also used in various industrial applications.
