Rail Dog Spike
What Are Dog Spikes
Rail dog spike, also known as plain cut spike, railroad & railway dog spike, is used to secure rails to wooden sleepers. The shank of the spike has a square cross-section, and its tip is chisel-shaped. It closely resembles a dog's head, hence it is known as a "dog spike." Some say that "it guards the rails as faithfully as a dog" — this is, perhaps, a literary exaggeration and tribute to the dog spike.
The spike is hammered directly into the timber sleeper, and the hooked head then clamps the edge of the rail base. Therefore, it features a simple structure, easy installation, and low cost, and it has become the most widely used rail fastener worldwide. We specialize in manufacturing railway dog spikes. We supply rail dog spikes in a comprehensive range of sizes and we can manufacture them in accordance with international standards such as DIN, GOST, EN, AREMA, GB, JIS, and TB. Customized solutions according to your drawings or samples are also available. Feel free to contact us.
