Compared to traditional dog spikes, screw spikes offer multiple performance advantages. GNEE RAIL can provide not only dog-head spikes but also various types of screw spikes, such as the Ss series Sleeper Screw, Square head screw spike, and Hexagon screw spike. In addition to standardized products, we also offer customized solutions based on customer requirements.
First, screw spikes offer superior holding force. GNEE RAIL's chair screw feature a helical structure that tightly engages with the sleeper, providing a more stable connection. This design is particularly suitable for applications involving dynamic loads.
Rail screw produced by GNEE RAIL exhibit excellent resistance to loosening. Vibrations generated by passing trains often cause traditional spikes to gradually loosen, but the helical structure effectively counters this tendency, reducing maintenance frequency. The "self-locking" feature of the threads ensures the spike remains securely fastened even under vibrational conditions.
Our lag bolt also demonstrate excellent adaptability and can be used with various sleeper materials, including wood, concrete, and composite materials. Additionally, the installation process for screw spikes generates lower axial forces, significantly reducing the risk of sleeper cracking. They are also relatively easier to remove, facilitating track maintenance and component replacement.
