Product Description

Product Description

 

The screw spike, an essential component in railway construction, is also known as a rail screw. Esteemed as a vital type of Rail spike, this component epitomizes durability and precision.It serves as a robust metal screw, specifically designed for securing rail fasteners with unyielding strength.Crafted predominantly from high-grade NO.3 steel, the unique design features a threaded nail rod surface, thus earning the moniker of a screw spike. Its pull-out resistance surpasses that of a common rail spike by 0.5 to 1.0 times, although its thrust resistance is reduced by 50%. Despite the challenges in assembly and disassembly, and the complexity in adjusting the rail gauge, screw spikes are predominantly utilized in the railway turnout, where reliability and performance are paramount.Its integration is indispensable.

To accommodate the diverse demands of our clientele, we proudly offer an extensive array of customizable solutions including coach screws, stud screws, railway sleeper screws, and bespoke screw spikes tailored for railway applications.
In terms of cost considerations, screw spikes necessitate a higher investment than dog spikes, yet they offer the substantial benefit of enhanced fixation strength-approximately double that of a rail spike. They are further complementable with spring washers for optimal efficacy.

To ensure uncompromised quality, rigorous screw testing is imperative at the onset of the wire rod stage. The caliber of a precision screw is intrinsically linked to the quality of the wire used in its production.

The subsequent phase focuses on a meticulous inspection of the head screw forming. The integrity of the mould is critical in this process; a superior mould is foundational for manufacturing an impeccable screw spike. Following this, an evaluation of the screw spike production machinery is conducted to guarantee safety and efficiency. Each formed screw spike undergoes a thorough inspection for burrs and precise measurement to ascertain size accuracy.

The third stage entails an exhaustive examination of the screw thread. The thread pitch detection must align with both customer specifications and international standards to ensure excellence.
Concluding the process is the decisive screw shipment inspection. This involves the meticulous selection of only the highest quality screw spikes for our esteemed customers, ensuring a product that upholds our commitment to superiority.
