Rail sleeper screw spikes are used to fasten sole plates and ribbed base plates to wooden sleepers.
In rail construction with the concrete sleepers, the rail sleeper screw is used in combination with a
plastic dowel pressed in the concrete sleeper, indirect or direct fastenings of rails on concrete and
wooden sleepers. Characteristically, the sleeper screw thread may only be produced in a hotforming
operation. The different shapes of the head correspond to the pass form of the respective spanner
used for fastening and loosening of the rail sleeper screws.
The screw spike costs more to manufacture than the dog spike or dog nail, but has the advantage of
greater fixing power; approximately twice that of a dog spike, and can be used in combination with
spring washers.
