Product Description

Product Description

 

The screw spike, an essential component in railway systems, is alternatively known as rail screw. This vital hardware falls under the category of Rail spike, a robust metal fastener designed for securing rail fasteners. Constructed primarily from high-quality NO.3 steel, the screw spike features a threaded surface which distinguishes it from conventional spikes. Its pull-out resistance is notably 0.5 to 1.0 times greater than that of a typical rail spike, although its thrust resistance is reduced by 50%. Despite potential challenges in rail gauge adjustments due to its design, screw spikes are predominantly utilized in railway turnouts.

To cater to the diverse requirements of our clients, we offer an extensive range of products including coach screws, stud screws, railway sleeper screws, and custom screw spikes tailored for railway applications.
While the cost of screw spikes surpasses that of dog spikes, they provide superior fixing capability, nearly doubling the security offered by standard rail spikes. Furthermore, their design facilitates use with spring washers for enhanced stability.

Commencing the production process, screw testing is vital and should be initiated at the outset of wire rod production. The precision of these screws is crucial and directly impacts the overall quality and efficiency of wire production.

The next phase involves the meticulous inspection of head screw formation. Mould testing plays a pivotal role in the screw spike formation process. A superior mould is foundational to producing high-caliber screw spikes. Following this, the production machinery undergoes rigorous evaluation to ensure safety and efficiency in production. Formed screw spikes are then inspected for burrs and precisely measured to confirm size accuracy.

The subsequent stage focuses on thorough detection of screw threads, ensuring that they meet both customer specifications and international standards for pitch and precision.
Finally, the screw shipment inspection process involves the meticulous selection of only the highest quality screw spikes for delivery, ensuring that customers receive products of unparalleled excellence.
