In railway track systems, track spikes serve as critical fastening components primarily used to securely fix steel rails to sleepers. Among these, Dog Spikes and Screw Spikes are two common types, each differing in structure, installation method, and application scenarios.
Dog spikes feature a distinctive "dog head" shape at the top and are typically hammered directly into wooden sleepers. They are widely used in light rail, industrial tracks, and certain low-speed railway lines due to their quick installation and cost-effectiveness. While they offer economical and rapid deployment advantages, their stability is comparatively lower, making them suitable for applications where high spike pull-out resistance is not critical.

In contrast, screw spikes incorporate a threaded design that allows them to be screwed into sleepers, creating a more secure connection. These are ideal for concrete sleepers or track systems requiring higher clamping force. Compared to dog spikes, screw spikes demonstrate superior pull-out resistance and anti-loosening performance, making them common in heavy-haul railways, high-speed rail lines, and mountainous railway sections.
