Loctite Threadlocker Red 271 is designed for the permanent locking and sealing of threaded fasteners. We recommend this for securing gas block set screws.

The product cures when confined in the absence of air between close-fitting metal surfaces. It protects threads from rust and corrosion and prevents loosening from shock and vibration. It is only removable once cured by heating up parts to 500°F (260°C).

  • Prevents rusting of threads
  • Permanent seal, prevents tampering
  • Prevents loosening of metal fasteners caused by vibrations
  • Protects threads
  • High strength
  • Locks threads
