HARDEX Thread-Lok 6277 Heavy Duty & Bolt Lock

DESCRIPTION


HARDEX Thread-Lok 6277 is a high-strength, permanent anaerobic thread locker designed for heavy-duty applications. Its red-colored, high-viscosity formula (5,000–6,000 cps) effectively fills gaps up to 0.40mm, ensuring robust bonding on coarse-threaded fasteners. Once cured, it resists loosening due to vibration, shock, and thermal cycling, making it ideal for securing components that require permanent assembly. 
 

Key Features:

  • Permanent Thread Locking: Provides a durable bond that prevents loosening under extreme conditions.

  • High Strength & Viscosity: Suitable for coarse-threaded fasteners up to M36, with excellent gap-filling capabilities.

  • Temperature Resistant: Maintains performance in high-temperature environments; heat may be required for disassembly.

  • Corrosion Protection: Seals threads to prevent rust and corrosion.

  • Versatile Applications: Ideal for use on bearing shafts, flanges, piston rods, furnace studs, and other heavy-duty components.
     

📌 Recommended Applications:

  • Loose-fitting bearing shafts

  • Flanges and piston rods

  • Big plant furnace studs

  • Locking bolts and studs up to M36
