Chain guard screws are essential, low-load fasteners. They must stay secure against constant chain and engine vibration, yet they are the single most frequently accessed fasteners on the drivetrain. Removal is mandatory for routine chain maintenance, cleaning, and lubrication. This application demands the absolute lowest level of thread locking strength to guarantee quick, non-destructive disassembly while preventing vibration-induced back-out.

The Professional’s Choice: INCURE Re-Lok™ B22 Purple Threadlocking Adhesive (Light Duty)

1. Engineered for Safe, Frequent Disassembly

The B22 (Purple) is formulated with a Low Strength profile, providing just enough resistance to vibration to prevent accidental loosening, but allowing the screws to be easily broken and removed using minimal torque from standard hand tools. This protects the plastic, aluminum, or thin metal threads of the guard and frame mount from stripping—a common issue when stronger threadlockers are misapplied.

2. Stops Vibration-Induced Loosening

Despite their low load, chain guard screws are subject to high-frequency vibration transmitted from the chain and engine, making them prone to loosening. The B22 fills the microscopic gaps in the thread, ensuring the screw remains securely fastened between maintenance intervals, preventing the guard from rattling or falling off.

3. Controlled Lubricity for Small Fasteners

The B22 is specifically designed for small fasteners (typically M6 and smaller) and provides controlled lubricity, which ensures the screw achieves an accurate and consistent clamp load during assembly, guaranteeing the guard is seated correctly without overtightening.

By choosing INCURE Re-Lok™ B22, you ensure your cosmetic and service fasteners remain secure against vibration while maintaining the highest possible maintenance efficiency and protecting delicate threads.
