Product Description

Product Description

 

The screw spike, often referred to as a rail screw, represents a unique class of Rail spike. This robust metal screw securely fastens rail fasteners. Typically constructed from high-quality NO.3 steel, its threaded nail rod earns it the name 'screw spike'. It boasts an impressive pull-out resistance that is 0.5 to 1.0 times greater than standard rail spikes, although its thrust resistance is reduced by 50%. Its design complexity means adjustments to the rail gauge are a challenge, making it perfect for use on the railway turnout.

To cater to diverse client requirements, we offer an array of options including coach screws, stud screws, railway sleeper screws, and bespoke screw spikes tailored for railways.
Although the screw spike incurs a higher cost compared to the dog spike, it delivers superior fixing power-nearly double that of a conventional rail spike-and can be effectively paired with spring washers.

Initially, rigorous screw testing must be conducted at the inception of the wire rod production process. The precision quality of these screws is fundamentally linked to the wire production standards.

Subsequently, it is crucial to perform a thorough inspection of the head screw forming process. Ensuring the mould quality is paramount for achieving an exemplary screw spike. Following this, the production machine's inspection ensures safe and seamless manufacturing. Post-formation, screw spikes must be checked for any burrs and meticulously measured to confirm precision sizing.

The third critical phase involves detecting and verifying the screw thread. This includes ensuring the thread pitch aligns with both customer demands and international quality standards.
The final stage involves a meticulous screw shipment inspection, where only the finest screw spikes are selected, ensuring customers receive the highest quality products.
