IC-Loc Red - Permanent Thread Locker - Threadlock - BSI Adhesives Available Sizes:
BSI-173: .34 Fl. oz (10 ml)
BSI-174: 1.69 oz. (50 ml)

IC-LOC™ Red is a medium thickness, high strength threadlock that is applied to the threads of fasteners before assembly. Once the IC-LOC Red™ is cured, the fasteners are permanently together and cannot be disassembled. IC-LOC Red™ will maintain its strength up to 490° F.

Works Good On:

  • Threads of fasteners
  • Threads that need permanent bond


Shake well and then apply IC-LOC™ Red to the clean and dry threaded areas before assembling non- plastic parts. Product sets in 10 minutes, with full cure within 24 hours. IC-LOC™Red is anaerobic and cures in the absence of air, which occurs when a bolt, screw or nut is tightened. IC-LOC™ Red permanently prevents the loosening of threaded fasteners from shock and vibration, while sealing and preventing the rusting of threads. Cured temperature range is -60° to +300°F (-51° to +149°C). Locked fasteners are only removable by heating them to 490°F (254°C). Remove residue with a damp cloth.
