Railroad spikes, also known as railway spikes, are an important component of railroad infrastructure. They are used to secure rails to the underlying crossties, which in turn are attached to the ballast bed. Without these spikes, the rails would shift and become unstable, causing accidents and derailments.
Coach screws are specifically designed fasteners used to secure rails to the underlying railway sleepers or ties. They are typically made of high-strength materials such as carbon steel or stainless steel to withstand the demanding conditions of railway environments. The construction of a coach screw consists of a threaded shank, a head, and in some cases, a flange or square neck.
