The Vossloh W14 Screw Spike, also known as a sleeper screw or tirefond, is a vital component of the highly popular Vossloh W 14 rail fastening system for ballasted tracks. This system, used in over 60 countries, is designed for both conventional rail and high-speed lines (up to 320 km/h).
Key Features & Specifications
Key Features & Specifications
The screw spike provides the essential anchoring force, working in conjunction with other components to ensure the rail remains securely fastened to concrete or wooden sleepers.
Material: The screw spikes are typically manufactured from high-strength carbon steel, with available grades including 4.6, 5.6, and 8.8.
Corrosion Protection: Various surface finishes are available to enhance durability and corrosion resistance, such as plain oiled, black oxide, galvanization (including hot-dip), Dacromet, and sherardized coatings.
Function: It secures the Skl 14 tension clamp and angle guide plates to the sleeper. The system provides a high nominal clamping force of at least 8 kN per clamp and excellent longitudinal rail resistance of a minimum of 9 kN.
Performance: The W14 system is known for its durability and wide application, accommodating maximum axle loads of up to 260kN (26 tonnes) and adhering to the EN13481-2 standard.
Dimensions: Standard dimensions can vary by manufacturer and specific application requirements (e.g., M24×150mm, M24×160mm, M24×180mm), with specifications tailored to the track system.

A complete set of the Vossloh W 14 fastening system typically includes the following items per fastening point:
2 pcs Tension clamp Skl 14
2 pcs Screw spike Ss 35/Uls 7 (or similar designation based on standard)
2 pcs Angled guide plate Wfp 14K (e.g., Wfp 14k 12 or Wfp 14k 14.5)
1 pcs Rail pad (e.g., ZW686a, made of EVA or TPU elastomer to damp vibrations)
1 or 2 pcs Plastic dowel (pressed into the concrete sleeper to receive the screw spike)
2 pcs Flat washers UIs 7 (used with the screw spikes)
The system's innovative mid-loop design of the Skl 14 clip provides flexibility and helps prevent rail rotation, contributing to increased safety and travelling comfort.
