Product Description

Product Description

 

The screw spike is also known as: rail screw. As one distinguished type of screw spike, it plays a vital role Rail spike,a metal screw whose primary function lies in the secure fastening of rail fasteners.The screw spike, typically constructed from NO.3 steel, features a threaded nail rod surface, granting it the name 'screw spike'. Its pull-out resistance impressively outperforms that of standard rail spikes by 0.5 to 1.0 times, though its thrust resistance is 50% less due to its intricate threading. The complexity of installation and removal makes it less adaptable for rail gauge adjustments, hence it is ideal for use in the critical structures of the railway turnout.

To cater to the diverse requirements of our clients, we provide an extensive range of options including coach screws, stud screws, railway sleeper screws, and other bespoke screw spikes tailored for railway applications.
While the screw spikes come with a higher cost than traditional dog spikes, they offer the superior advantage of enhanced fastening power-nearly double that of a conventional rail spike-when paired with spring washers, making them a worthy investment in durability and performance.

Initially, the screw testing should commence at the very start of the wire rod process. The precision of these screws is fundamentally linked to the wire's production quality.

The next crucial phase involves an inspection of the head screw forming process. Mould testing is paramount to this stage, as a superior mould is crucial for producing high-quality screw spikes. Subsequently, an evaluation of the screw spike production machinery is pivotal to ensuring a safe and seamless manufacturing process. The formed screw spikes must be scrutinized for any burr presence and measured meticulously for dimensional accuracy.

The third phase focuses on the meticulous examination of the screw thread. It is imperative that the thread pitch complies with both customer specifications and international standards.
The final step entails a stringent inspection prior to shipment. This process involves meticulously sorting through and removing any non-conforming screw spikes, thus ensuring only the finest quality products are delivered to our esteemed customers.
Size: Meticulously designed to the specifications of M20*110, ensuring optimal performance and reliability in demanding railway environments.
