24x230mm Ss36 Sleeper Screw

are typically secured in pre-drilled holes in sleepers, and in some cases, paired with embedded plastic dowels-this design makes them especially suitable for rails installed on wooden sleepers.

Their specifications, including thread profile, length, diameter, and drive head type, can be adjusted to meet specific regional or project requirements. Common classifications of screw spikes include four main types: Ss series sleeper screws, square-head screw spikes, hexagon-head screw spikes, and double-head screw spikes.

The 24×230mm Ss36 sleeper screw is a key fastener in railway fastening systems, primarily used in high-speed rail W300-1 type fastening systems to securely connect rails to wooden or concrete sleepers. Made from high-quality steel, the screw provides high strength, excellent toughness, and outstanding corrosion resistance, ensuring long-term performance under high-frequency train operations and heavy-duty railway conditions. GNEE RAIL offers multiple surface treatments, including hot-dip galvanizing, zinc plating, black oxide, and oiled finishes to meet diverse environmental requirements.

The 24×230mm Ss36 screw has a length of 230 mm with a standard triangular thread, ensuring a secure connection with the rail system. It is suitable for a rail height adjustment range of approximately +29～+38 mm and can be customized according to specific track design requirements. The square head design allows compatibility with spring washers or flat washers, enhancing track stability and preventing loosening.

Ss36 sleeper screws are widely used in high-speed railways, urban subways, heavy freight lines, and industrial railway tracks. Their high strength and corrosion resistance enable them to perform reliably in complex environments such as coastal areas, high-humidity regions, tunnels, bridges, and ports.
