What is a 3V screw spike?
A 3V screw spike is a type of rail screw spike that is a medium or large metal screw with a threaded nail rod surface and a head with a square or rectangular section. 3V screw spike is also known as a 3V sleeper screw. It is used to fasten rails and sleepers in railways. 3V screw spikes meet the requirements of NF F50-006. 3V screw spikes have two grades, grade 4.6 and grade 5.6.

3V Type Railway Sleeper Screw vs DHS35 Railway Screw Spike
The 3V Type Railway Sleeper Screw (like V20, V23) and DHS35 are both threaded fasteners for securing rail to sleepers, but they differ in standards, dimensions, and applications: 3V types follow UIC/French standards (NF F 50006) for wooden/concrete sleepers with varying diameters (e.g., M20, M23) and lengths, while the DHS35 is a specific design (often 24mm diameter) used in systems like SKL14, offering high tension but less gauge adjustment than common spikes, suited for wooden or concrete sleepers with plastic dowels, often with large disk heads for high pull-out resistance in various climates.
DHS35 Railway Screw Spike
- Design: A particular model within a family of screw spikes, often associated with the SKL14 fastening system.
- Dimensions: Commonly 24mm in diameter and around 158-161mm long.
- Material/Grade: High-tension steel, providing excellent pull-out resistance.
- Application: Also used for wood and concrete sleepers, often with large disc heads.
- Characteristics: High pull-out strength, with a design that allows for some adjustment but less than standard cut spikes.
What is the purpose of a railroad spike?
The purpose of a railroad spike is to secure steel rails to wooden or concrete ties, ensuring track stability and maintaining the correct distance (gauge) between rails to prevent derailments, acting as a vital component for safe train operation. These large, steel fasteners are hammered or screwed into ties, holding the rail base firmly against the sleeper for reliable railway transport.
Key Functions:
- Fastening: They physically attach the rail to the sleeper (tie), forming the foundation of the track.
- Gauge Maintenance: They help keep the two rails at the precise, consistent distance needed for wheels to run smoothly.
- Stability: By securing the rails, spikes prevent lateral movement and absorb some shock, increasing overall track stability and safety.
