The wheel hub is the single most dynamically stressed component on any vehicle or machine. Wheel hub bolts operate under a constant, brutal assault: they absorb immense lateral force during cornering, extreme shock from road impacts, relentless rotational vibration at high speed, and massive thermal cycling due to braking. Failure of a single wheel hub bolt is a zero-tolerance event, leading directly to wheel separation, catastrophic damage, and a life-threatening safety crisis.

For the engineering professional, securing these bolts is the ultimate act of liability mitigation and performance assurance. This demands a bond that is permanent, high-strength, and thermally and chemically resilient.

This is the non-negotiable territory of the INCURE Re-Lok™ Red Series—featuring the B72 Heavy Duty and B77 Extreme Duty Threadlocking Adhesives. They are engineered to create a structural unity that simply cannot loosen under dynamic stress.

The Problem: The Combined Forces that Defeat Standard Fastening

Are your wheel hub assemblies vulnerable to these high-stakes threats?

• Vibrational Self-Loosening: The constant, high-frequency rotation and impact shock rapidly overcomes friction and causes conventional locks (washers, clips) to fail.
• Brake Heat Degradation: Intense and localized heat generated during braking can soften or weaken standard adhesives, leading to loss of clamp load.
• Corrosive Fretting: Water, salt, and brake dust ingress initiate fretting corrosion, welding the bolt to the hub and eventually compromising the metal’s strength.

Only a permanent, anaerobic lock can eliminate the internal micro-movement that leads to these failures.

The Position: Permanent Security Engineered for Dynamic Stress

The INCURE Re-Lok™ Red Series is the defined solution for permanent, high-strength applications in environments dominated by dynamic loading and thermal stress. By completely filling all microscopic voids between the threads, the cured adhesive transforms the two components into a single, unitized metal assembly, locking the bolt against the complex forces of wheel rotation and impact.

Here is the strategic defense the Re-Lok™ Red Series offers for wheel hub bolts:

1. INCURE Re-Lok™ B72 Red Threadlocking Adhesive – Heavy Duty

The High-Heat Specialist for Braking Zones.

In high-performance or heavy-duty vehicles, the wheel hub sits directly next to the braking system, leading to significant temperature spikes. The B72 (Heavy Duty) is the definitive choice here. Its key feature is its ability to maintain its permanent, high-strength lock under extreme operating temperatures up to 230∘C. This high-thermal resilience guarantees that the essential clamp load is maintained despite continuous, heat-induced expansion and contraction.

2. INCURE Re-Lok™ B77 Red Threadlocking Adhesive – Extreme Duty

The Corrosion and Shock Fortress.

Wheel hub bolts are perpetually exposed to environmental hazards. The B77 (Extreme Duty) is engineered for maximum protection against degradation. Its high viscosity formulation ensures superior gap filling for maximum shear resistance, while its excellent chemical resistance creates an impenetrable seal against water, road salt, and corrosive fluids. This prevents fretting corrosion, ensuring the long-term integrity and strength of the threads.
