In the high-stakes world of railway infrastructure, where safety margins are measured in millimeters and vibrations threaten relentless wear, choosing the right fastening component isn't just a specification – it's a commitment to long-term integrity. Enter the SS35 Screw Spike, a cornerstone of modern track fastening systems, engineered to deliver unparalleled holding power, durability, and resistance to the harshest operational demands.
Why SS35 Screw Spikes Are Critical for Track Performance & Safety:
Absolute Grip, Zero Creep: Designed to bite deep and hold fast, preventing rail base movement (creep) under dynamic train loads, maintaining precise track geometry.
Vibration & Loosening Resistance: Engineered threads and installation torque ensure exceptional resistance to vibration-induced loosening, a common failure point in lesser fasteners.
Superior Pull-Out Strength: Provides significantly higher resistance to vertical uplift forces compared to traditional spikes or dog spikes, crucial for high-speed lines and heavy axle loads.
Foundation for Elastic Systems: Integral to modern elastic fastening systems (e.g., using baseplates/e-clips), enabling controlled rail movement while maintaining constant clip pressure.
Enhanced Corrosion Protection: Available with advanced coatings (HDG, BIM) for extended service life, even in coastal or high-pollution environments, reducing maintenance frequency and lifecycle costs.
