BSI IC-Loc Red Threadlocker – Medium-High Strength 1/3 oz BSI173

The BSI IC-Loc Red Medium-High Strength Threadlocker (BSI173) is a high-strength anaerobic adhesive for locking threaded fasteners that are not intended for frequent removal. The red formula provides a stronger, more permanent lock than blue threadlocker — ideal for fasteners on drivetrain components, motor mounts, and other high-vibration areas where you want maximum retention. Disassembly requires the application of heat.

Key Features

• Medium-high strength — stronger and more permanent than blue threadlocker
• Anaerobic cure — cures in the absence of air when fastener is tightened
• Maximum vibration resistance for high-stress fasteners
• Ideal for drivetrain, motor mount, and structural fasteners
• Requires heat for disassembly — use on fasteners not requiring frequent removal
