What are the unique advantages of screw spikes compared to dog spikes?
Screw spikes have unique advantages over dog spikes due to their higher holding power, lower sleeper damage, and reusability. Their threaded design provides a superior grip, approximately double that of a dog spike, and they do not split wooden sleepers during installation. They can also be easily unscrewed and reused, which makes maintenance more efficient.
Key advantages of screw spikes
- Superior holding power: The screw threads create a much stronger and more secure grip in the sleeper, providing more than twice the holding power of a dog spike.
- Less damage to sleepers: Unlike driven dog spikes, which can split wooden sleepers, screw spikes do not cause this type of damage.
- Reusability: Screw spikes can be unscrewed and reused in the same hole without damage, which improves cost-efficiency and makes maintenance faster and simpler.
- Increased maintenance efficiency: Their reusability means they can be easily removed and re-tightened with a wrench, which reduces repair time.
- Compatibility with spring washers: Screw spikes can be used in combination with spring washers, which can further improve track stability.
Screw spikes specification
At before, the screw spikes are usually used to fasten the ribbed base plates and sole plates to wood sleepers. With the construction and development of the concrete sleepers, the screw spikes play an important role in railway fastening systems with the help of a plastic dowel. In order to meet the different use and standards of railway tracks, the screw spikes can be classified into so many types. Now all railroad spikes are made out of carbon steels. Through the different specific geographic requirements such as lengths, diameters, drive heads and thread profiles, the railway screw spikes can be classified into four types: Ss series sleeper screw, square head screw spike, hexagon screw spike and double-head screw spike.
