A 45# screw spike is a high-performance railway fastener designed to firmly secure steel rails to railway sleepers (railroad ties).Manufactured from 45# high-quality carbon structural steel, this type of spike belongs to the hexagon-head screw spike category and is widely used in rail fastening systems for heavy-load and high-speed railway applications.
The screw spike features a threaded shank with helical grooves, enabling it to be screwed directly into wooden, composite, or pre-drilled concrete sleepers. This design ensures a tight fit, reduces track movement, and enhances the stability of the railway track structure.
45# carbon steel offers excellent tensile strength, wear resistance, and durability, making the 45# screw spike capable of withstanding high loads, vibrations, and harsh environmental conditions. GNEE RAIL uses strict quality control and precision machining to produce screw spikes that meet AREMA, UIC, and TB/T railway standards for both freight and passenger lines.
