Threadlockers

Thread-locking compounds, also known as threadlockers, are adhesive substances used to secure threaded fasteners and prevent them from loosening over time. Thread-locking compounds are single-component adhesives applied to the threads of fasteners like screws, bolts, and nuts. Most thread-lockers are anaerobic epoxies, meaning they cure in the absence of oxygen when confined between metal surfaces.Thread-lockers come in different strengths, and they are typically color-coded to indicate their strength. These strengths and their color code are as follows: Low-strength (purple), Medium-strength (blue), High-strength (red)


Common applications of Threadlockers are:

  • • Automotive
  • • Machinery
  • • Electronics
  • • Aerospace
  • • Industrial
  • • Residential
