Top drive bolts are mission-critical fasteners in modern drilling systems, ensuring structural integrity under extreme torque (10.21-129.72 kN·m) and harsh environments (operating range: -50°C to +420°C)15. Designed for compatibility with leading top drive models like NOV Varco TDS-4H, TDS-11SA, IDS-1, and TESCO 150HMI/650ECI, our bolts are engineered to secure high-wear components including:
1.Sliding sleeves & wear plates
2.Gearbox assemblies
3.Hydraulic IBOP (Inside Blowout Preventer) actuators
4.Bearing housings and motor mounts
