A railroad spike is used on rail track to fix the rails, which is completely made of iron or steel. It is thought as a kind of key rail accessories for safety of railway transportation. Common raw materials of steel include: Q235, 45#, 40Cr, 35CrMoA, Q345B, Q345D and 20MnTiB etc.
A rail screw spike, also called sleeper screw, rail screw or lag bolt, is a medium or large metal screw used to fasten a rail base plate or rail.
Screw spikes play important roles in multiple fields,To better understand the applicability of screw spikes, a simple comparison with several common fasteners can be made:
Straight-Shank Spikes: Low cost but weak pull-out resistance, suitable only for light-load scenarios.
Expansion Bolts: Ideal for concrete substrates but complex to install and not reusable.
Anchor Bolts: High load-bearing capacity but require embedding and curing, resulting in longer construction periods.
In comparison, screw spikes offer a more balanced performance in terms of installation efficiency, environmental adaptability, and cost-effectiveness.
With their scientific design and reliable performance, screw spikes have become an indispensable fastening solution in modern engineering. Whether for professional construction or temporary facilities, rational selection of screw spikes can significantly enhance the stability and durability of projects.
