Why is it called a dog spike?
It's called a dog spike because the two lugs on its head resemble a dog's head. Another theory suggests the name comes from the spike's ability to "guard" the railway tracks loyally like a dog.
The name's origin: The primary reason for the name is the appearance of the spike's head, which has two lugs on either side that give it the look of a dog's head.

- The ordinary railroad spikes are divided into manual spikes and mechanical spikes. These two kinds of spike are the simplest in the process of installation and use, and can be directly fixed by using a nail.
- However, these two types of railroad spikes are very different in terms of production process. The manual spikes are a relatively early production for railroad spikes. This production uses the method of hand-made to make sure the hot embryo forming of railroad spike, so the railroad spikes manufactured by this production process may have certain defects, for example, the surface of the spikes may have some convex or burrs. There are also some spikes that have more or less weight.
- Compared with manual spike, another common railroad spike can avoid these problems very well, that is, the mechanical spike. The production process of mechanical railroad spikes is a combination of manual and mechanical production. Commonly, the mechanical railroad spike has a smooth surface and the weight of each spike is not much different. The mechanical railroad spikes can be better used in batches, and the problem of high defective products like ordinary manual spikes does not occur.
- Manual spikes and mechanical spikes are similar in the installation and maintenance process during use, but the mechanical spikes have strict standards and no defective requirements. At the same time, the nails of the mechanical spikes are smoother, which makes it less prone to accidents during transportation, so it is very popular among railway workers.
Comparison of dog spikes and screw spikes
Surface
The screw spikes are the railroad spikes with the screw thread on the surface. But as to the dog spikes, it has a pointed penetrating head with a smooth suface.
Power
As to the holding power, the screw spikes can provide more than twice of the power than the dog spikes.
Cost
Because of the greater fixing power and the feature that can be combined with spring washers, the cost of manufacture of the screw spike is higher than the dog spikes or dog nails.
