Sleeper Bolts: The Critical Fasteners Powering Railway Infrastructure
Sleeper Bolts (also called Rail Bolts or Tie Bolts) are high-strength, precision-engineered fasteners designed to securely connect rails, sleepers (ties), fishplates (joint bars), and other track components in railway systems. They ensure track stability, safety, and longevity under extreme operational stress.
Key Features & Benefits
Extreme Strength & Durability
Made from high-tensile alloy steel (Grade 8.8, 10.9, 12.9) or corrosion-resistant stainless steel (304/316).
Withstands dynamic loads (e.g., 30-ton axle loads), vibration, and impact without deformation or failure.
Vibration-Proof Security
Integrated anti-loosening technology (e.g., nylon-insert locknuts, serrated flanges, or pre-applied threadlocker) prevents bolt loosening under constant train-induced vibrations.
Corrosion Resistance
Hot-Dip Galvanized (HDG) or stainless steel coatings resist rust from rain, ballast abrasion, de-icing salts, and pollutants.
Lifespan: 20–30+ years in harsh environments, reducing maintenance frequency.
Compliance & Safety
Manufactured to global railway standards (e.g., AREMA Chapter 30, EN 15048, BS EN 14399).
Full traceability with material certifications for quality assurance.
