Product Description

Product Description

 

The screw spike is also known as a rail screw. As one of the pivotal components in railway fastening systems, the Rail spikeserves as a robust metal screw for effectively securing rail fasteners. Crafted primarily from high-quality NO.3 steel, the screw spike is distinguished by its threaded nail rod surface, a design that enhances its pulling resistance by 0.5 to 1.0 times compared to standard rail spikes, though its thrust resistance is reduced by 50%. Despite the challenges in disassembly and assembly that complicate gauge adjustments, it is predominantly utilized at railway turnoutswhere its performance is paramount.

To cater to a diverse clientele, we manufacture a wide array of fasteners, including coach screws, stud screws, and custom railway sleeper screws, ensuring tailored solutions for every railway need.
While the cost of screw spikes exceeds that of dog spikes, their superior holding capacity-approximately double that of a traditional rail spike-makes them invaluable, especially when used alongside spring washers for enhanced stability.

Initially, rigorous testing of the wire rod marks the commencement of the screw spike's precision journey, as its quality is intrinsically linked to the fundamental wire production process.

Subsequently, the head screw forming undergoes meticulous inspection. The integrity of the mould is crucial, serving as a foundation for producing superior screw spikes. This is followed by a thorough examination of the production machinery to ensure operational safety and efficiency, with a focus on detecting any burrs and verifying precise dimensions in the shaped screw spikes.

The third phase emphasizes the meticulous detection of screw threads, ensuring conformity with both customer specifications and international benchmarks for optimal performance.
The final step involves a comprehensive inspection before shipment, meticulously filtering out any non-conforming screw spikes to guarantee that only the highest quality products reach our esteemed customers.
