Winch mounting bolts are subjected to one of the highest intermittent tensile and shear loads a fastener can face. During a recovery or pull operation, these bolts endure massive, sudden forces, as well as constant vibration and shock during vehicle operation. Failure of a single mounting bolt can result in the winch tearing free of the vehicle—a catastrophic safety hazard and guaranteed vehicle damage. This demands an absolute, High Strength, Permanent lock.

For the off-road, heavy equipment, or marine professional, securing these bolts is the ultimate act of safety assurance and equipment protection.

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 unified, load-bearing structure that cannot fail under maximum winch load.

The Problem: Maximum Tensile Force and Dynamic Shock

Are your winch assemblies secured against these critical threats?

• Maximum Tensile Failure: During a hard pull, the bolts endure immense forces that relentlessly try to strip the threads and back them out.
• Off-Road Shock and Vibration: Continuous low-frequency shock from rough terrain constantly works to loosen the fasteners.
• Environmental Corrosion: Bolts are often exposed to water, mud, salt, and debris, which compromises the threads’ integrity.

Only a permanent, high-strength anaerobic lock can eliminate micro-movement and guarantee structural stability under maximum winch load.

The Position: Permanent Security for Extreme Load Applications

The INCURE Re-Lok™ Red Series is the defined solution for permanent, high-strength applications where structural failure is catastrophic. By curing into a durable thermoset plastic, the threadlocker completely fills all microscopic voids, transforming the mounting assembly into a single, unified, load-bearing component.

Here is the strategic defense the Re-Lok™ Red Series offers for winch mounting bolts:

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

The High-Temperature and Anti-Fatigue Lock. 

Winch motors and nearby components can generate significant heat during operation. The B72 (Heavy Duty) is essential for its ability to maintain its permanent, high-strength lock under extreme operating temperatures up to 230∘C (446∘F), ensuring the critical bond remains intact despite heat and continuous vibration.

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

The High-Viscosity and Structural Fortress. 

The B77 (Extreme Duty) is engineered for maximum overall resistance to dynamic shear and tensile loads. Its high viscosity formulation ensures superior gap filling for maximum resistance against the immense pull forces, while its excellent chemical resistance creates an impenetrable seal against environmental contaminants, protecting the threads from corrosion.

The Strategic Payoff

By investing in the targeted, high-performance security of the INCURE Re-Lok™ Red Series, you are making a non-negotiable commitment to safety and equipment reliability. You are guaranteeing the permanent security of the winch, eliminating the primary failure mode caused by extreme pull force and vibration.
