Rail Screw Spike Fastening System
Railway Screw Spikes are precision-engineered threaded fasteners manufactured from medium carbon or alloy steel, featuring a helical thread design with a forged head incorporating a square or hexagonal drive. These spikes are installed by rotation into pre-drilled timber sleepers or synthetic dowels embedded in concrete, providing mechanical interlock that delivers superior pull-out resistance while enabling removal and reuse during track maintenance operations.
Technical Specifications:
| Drive Type | Square Drive | Hex Drive | Internal Socket |
|---|---|---|---|
| Size | 25mm | 19mm | 14mm |
| Tool Type | Manual/Mechanical | High torque | Power tool |
| Torque Capacity | 200 Nm | 300 Nm | 250 Nm |
| Head Height | 25mm | 22mm | 18mm |
| Application | Timber sleepers | Concrete dowels | Limited clearance |
| Reuse Cycles | 3-5 times | 5-8 times | 3-5 times |
Installation & Maintenance Perspective:
- Square drive (25mm) accepts standard railway wrenches
- Hexagonal drive enables higher torque application
- Internal socket drives for reduced head protrusion
- Power tool compatibility for high-volume installation
- Manual wrench options for maintenance applications
Maintenance & Operational Perspective
- Coarse pitch threads optimize timber fiber engagement
- Thread root diameter exceeds shank for strength continuity
- Progressive thread depth improves withdrawal resistance
- Lead-in threads prevent cross-threading during installation
- Uniform helix angle ensures consistent torque conversion
