The hexagon screw spike's one head is a hexagon, which makes it easy to install and screw down, providing good fixed force and another end is the thread. They are suitable for railway systems needing relatively higher fixed force and stability, such as high-speed railways and high-volume railway lines. They especially apply to concrete sleepers and some modern railway construction.

Three different production process of spike
The most common rail spike is made of Q235 steel(China Steel Standard).The production process of the road spike is generally divided into machinery manufacturing, hand-made manufacturing and machinery & hand-made manufacturing combined.
Different production processes of the railroad spike need different technologies. For example, productions of screw spikes need the use of special steel and a variety of technologies for manufacturing. Manufacturers need to consider the production processes and productions of various different materials to offer the price to clients. Because of production technologies and productions, hand-made spike in all the spikes made of different materials becomes the lowest in production cost and it can also sell in bulk, but high quality railroad spike manufactured by machinery and complexity of production processes is in high cost itself and sell in quantity.
