Railway Rail Screw Spikes

Threaded spikes are the core fastening components used to fix rails in rail transit projects. They are mainly made of high-strength steel or stainless steel. Their threaded structure has the characteristics of enhancing stress resistance and delaying metal fatigue. They can be adapted to the pre-embedded casing of concrete sleepers or sulfur anchoring process.

Description

Technical Parameters

Definition & Purpose

Function: A threaded rail spike used to securely fasten rails to wooden or composite sleepers through mechanical interlocking.

Key Advantage: Provides higher pull-out resistance compared to dog spikes, making it suitable for heavy-load or vibration-intensive sections.

Technical Specifications

Parameter	Typical Value	Notes
Length	150–200 mm	Longer than dog spikes for deeper grip.
Thread Diameter	16–22 mm	Coarse threads (e.g., 4–6 threads per inch).
Material	Q235B, 45# steel, or alloy steel (e.g., 60Si2MnA).	Often hot-dip galvanized for corrosion resistance.
Tensile Strength	≥500 MPa	Higher than dog spikes (≥400 MPa).
Installation Torque	150–300 N·m	Requires torque-controlled tools.
