How much do you know about railway screw spikes?

As a professional manufacturer and supplier of railway fasteners, AGICO Rail can provide various specifications of railway screw spikes. Designed with high precision and processed under advanced technology, AGICO railway screw spikes are manufactured with high grade raw steel materials for almost the all specifications of railway screw spikes. With reliability, robustness and effective performance, railway screw spikes from AGICO Rail are widely used in railway engineering all around the world.
In general, railway screw spikes are used for fastening sole plates and ribbed tie plates to wooden railway sleepers. As to concrete railway sleepers, the railway screw spikes are used in combination with plastic dowel pressed in the concrete sleepers, indirect or direct fastenings of rails on concrete and wooden sleepers. The railway screw spikes may only be produced in a hot forming operation. The different shapes of the head correspond to the pass form of the respective spanner used for fastening and loosening of the railway screw spikes. Manufacturing railway screw spikes cost more than railway dog spikes, but railway screw spikes have many advantages, such as greater fixing power, approximately twice than that of dog spike and can be used in combination with spring washers.
