Product Description

Product Description

 

Our innovative screw spike, also referred to as a rail screw, stands out as a specialized Rail spike, meticulously engineered for securely fastening rail fasteners. Constructed with precision from NO.3 steel, this screw spike is renowned for its threaded surface, granting it superior pull-out resistance-up to 1.0 times greater than that of conventional rail spikes. While its thrust resistance is comparatively 50% less, the screw spike ensures unparalleled stability. Despite its complex assembly, making rail gauge adjustments challenging, it is predominantly utilized in the intricate railway turnoutsystems.

To cater to diverse client requirements, we offer an array of specialized screws including coach screws, stud screws, railway sleeper screws, and bespoke custom screw spikes crafted for the railway sector.
Although the production cost of these screw spikes is higher than that of dog spikes, they provide a remarkable advantage in terms of fixing power, offering nearly twice the holding strength of traditional rail spikes. Moreover, they can be effectively used alongside spring washers for enhanced stability.

Initially, stringent screw testing is essential, starting with the wire rod from which the screws are crafted. The precision quality of these screws is intrinsically linked to the wire production standards.

Subsequently, thorough inspection of the head screw forming begins. Conducting mould testing is paramount in the forming process, as a superior mould is the foundation of a high-quality screw spike. Following this, a detailed evaluation of the screw spike production machinery is conducted to ensure seamless and safe manufacturing. Each formed screw spike undergoes a meticulous check for burrs and precise size measurement to ensure exact specifications.

The third critical step involves meticulous detection of the screw thread. It is imperative that the thread pitch complies with both customer specifications and rigorous international standards to guarantee reliability.
The final stage is a comprehensive screw shipment inspection. This involves meticulously sorting out any non-conforming screw spikes to ensure that only the finest quality products reach our valued customers.
