The DHS35 screw spike is a specific type of spike for railway tracks.

I. Product features
High-quality material: Usually made of high-strength steel, it has excellent mechanical properties and can withstand huge pressure and impact force, ensuring the stability of railway tracks.
Spiral design: The unique spiral shape makes the combination between the spike and the sleeper tighter and more solid. During the installation process, the spiral part can be better embedded in the sleeper, enhancing the pull-out resistance and transverse resistance of the spike and effectively preventing the spike from loosening or falling off during train operation.
Accurate dimensions: The dimensions of the DHS35 screw spike are strictly designed and manufactured to ensure perfect cooperation with other components of the railway track system and ensure the geometric dimension accuracy of the track, providing guarantee for the safe and stable operation of trains.
Good corrosion resistance: After special surface treatment process, it has strong corrosion resistance and can be used for a long time in various harsh natural environments, reducing maintenance costs.

II. Application fields
It is mainly applied in various railway track systems such as main lines, branch lines, and special lines. Whether it is a high-speed railway where high-speed trains run or an ordinary railway undertaking freight transportation tasks, the DHS35 screw spike can play an important role.

III. Installation and maintenance
Installation: When installing the DHS35 screw spike, professional tools and equipment need to be used and the operation should be carried out according to the standardized installation process. First, ensure that the sleeper hole is clean and dry, then insert the spike into the hole and tighten the nut with a special wrench to firmly fix the spike on the sleeper. During the installation process, pay attention to controlling the tightening torque to avoid being too tight or too loose.
Maintenance: Regularly inspect and maintain the DHS35 screw spike, and timely find and deal with problems such as loose spikes, damage, and corrosion. For loose spikes, the nut should be tightened in time; for spikes with serious damage or corrosion, they should be replaced in time to ensure the safety and reliability of the railway track.

In conclusion, the DHS35 screw spike plays an important role in railway track construction and maintenance with its excellent performance and reliable quality.
