↵Rail Dog Spike Fastening System
The GNEE Elastic Rail Screw Spike is a high-performance mechanical fastener engineered to provide exceptional holding power and vibration resistance for railway tracks on wooden or composite sleepers. Featuring a threaded shank that mechanically locks into the sleeper material, this advanced fastening solution offers significantly greater stability than traditional dog spikes, making it ideal for mainlines, curves, and heavy-haul applications where track integrity is critical.
Technical Specifications:
