IC-Loc Blue - Thread Locker - Threadlock - BSI Adhesives Available Sizes:
BSI-171: .34 Fl. oz (10 ml)
BSI-172: 1.69 oz. (50 ml)

IC-LOC™ Blue is a medium thickness, medium strength threadlock that is applied to the threads of fasteners before assembly. Once the IC-LOC Blue™ is cured, the fasteners can be disassembled with standard hand tools if required.

Works Good On:

  • Threads of fasteners
  • Bolts
  • Screws
  • Nuts


Shake well, then apply IC-LOC™ Blue 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™ Blue is anaerobic and cures in the absence of air, which occurs when a bolt, screw or nut is tightened. IC-LOC™ Blue prevents loosening of fasteners from normal use and vibration, but parts can still be disassembled with hand tools. IC-LOC™ Blue seals and prevents rusting of threads. Cured temperature range is -60° to +300°F (-51° to +149°C). Remove residue with a damp cloth.
