Track spike, also known as rail spike, is a large nail with an offset head that is used to secure the rails and the base plate to the sleepers. In general, nails have different shapes and functions, such as dog spikes, screws, Ss series sleeper screws, square head screws, hexagonal screws, double-headed screws and other shapes. Among these various railway nails, dog spikes and screw nails are the two most common types.
Track spikes are made from carbon steel or stainless steel according to different utility. Meanwhile, the spikes’ surface can be plain, black, hot dipped galvanized, or galvanized to meet the customers’ requirement.
Dog spike has another name of cut spike. It features an L-shaped head that looks like a dog’s head and a with a square handle that is tilted to fit the top surface of the rail base. Typically, various sizes of nails are provided to meet the different requirements of the penetration length of the spikes. For smaller track sections, 5/8 "* 6" and 9/16 "* 5-1 / 2" are the two most common types of dog spikes, usually packed in 200 lb barrels or 50 lb kegs.
Screw spikes are usually used to fix concrete sleepers, so it is also called sleeper screw, rail screw or lag bolt. They can be screwed into the plastic ferrules casted in the concrete sleepers, or used in rails with wooden sleepers like in America and Canada. Unlike dog spikes, according to different international standards and specific geographical requirements, Screw Spikes are varied in thread profiles, length, diameter and drive head.
