Product Description

Product Description

 

The screw spike, revered throughout the industry, is commonly known as a rail screw. This innovative Rail spikeserves as a robust metal screw, purposefully designed for securing rail fasteners. Constructed from top-quality NO.3 steel, the screw spike stands out with its threaded nail rod surface, earning its distinct name. This feature grants it a pull-out resistance that is 0.5 to 1.0 times greater than the traditional rail spike, though its thrust resistance is reduced by 50%. Despite challenges in disassembly and rail gauge adjustments, its reliability makes it an ideal choice for railway turnouts.

To cater to the diverse needs of our clientele, we proudly offer coach screws, stud screws, railway sleeper screws, and custom screw spikes for railway applications.
In terms of cost, the screw spike is a premium investment compared to the dog spike, offering superior fixing power-approximately double that of a traditional rail spike. This spike can be adeptly used in tandem with spring washers for enhanced performance.

The initial phase involves meticulous screw testing at the onset of wire rod production. The precision of these screws is paramount and intricately linked to the quality of the wire production.

The subsequent phase necessitates rigorous inspection of the head screw formation. This involves mold testing, an essential step in the forming process of the screw spike. A high-quality mold is fundamental to crafting an exceptional screw spike. Thereafter, inspecting the production machinery is vital for ensuring efficient and safe production. Each formed screw spike is scrutinized for burr absence and accurately measured to assure precise dimensions.

The third pivotal phase focuses on the detection of screw threads. The thread pitch verification is stringent, ensuring compliance with both customer specifications and international standards.
The final phase involves a comprehensive screw shipment inspection. This process entails selecting only the highest quality screw spikes for delivery, ensuring that only the best are presented to the customer.
