How Much Do You Know About Railway Screw Spikes

Railway screw spikes are used to secure sole plates and ribbed tie plates to wooden railway sleepers. In the case of concrete railway sleepers, these screw spikes are used in combination with plastic dowels pressed into the concrete sleepers, allowing for both indirect and direct fastening of rails on concrete and wooden sleepers. The production of railway screw spikes is exclusively carried out through a hot forming operation. The different shapes of the screw head correspond to the specific spanner used for fastening and loosening the railway screw spikes. While the manufacturing cost of railway screw spikes is higher compared to railway dog spikes, they offer several advantages, such as greater fixing power-approximately double that of dog spikes-and the ability to be used in combination with spring washers.
