Engine mounting bolts are the critical link between the powertrain and the chassis. They operate in a hyper-stress environment: continuous, severe engine vibration, massive torque loads during acceleration and deceleration, and rapid thermal cycling as the engine heats up and cools down. A failure in these structural bolts is catastrophic, leading to dangerous engine movement, potential damage to vital fluid lines, and complete operational shutdown.
Don’t let shock loads or thermal stress compromise your vehicle or industrial machinery’s heart.
INCURE Re-Lok™ B72 Red Heavy Duty Threadlocking Adhesive
For the highest-stakes applications like engine mounts, a standard threadlocker won’t suffice. The INCURE Re-Lok™ B72 Red is a high-strength, anaerobic adhesive specifically engineered for extreme durability, providing reliable threadlocking where temperature and shock are at their peak.
| Feature & Benefit | Technical Insight for Engine Mounting Bolts | Conversion Value |
| Extreme Thermal Endurance | Engineered to withstand continuous operating temperatures up to 230°C, maintaining structural integrity even around hot engine blocks and exhaust manifolds. | Defy the Heat: Get a permanent lock that is impervious to extreme engine thermal cycles. |
| High-Strength, Heavy Duty Lock | Provides high-strength performance for large, critical fasteners up to M36, ensuring engine movement is perfectly dampened and contained. | Anchor the Power: Achieve absolute fastening security against shock and high-G forces. |
| Contaminant Tolerance | Designed to cure rapidly even on surfaces that are not perfectly clean, tolerating minor oil film or surface contaminants during assembly. | Simplify Maintenance: Get reliable performance without the need for perfect, time-consuming thread preparation. |
| Permanent Vibration Resistance | Cures into a rigid, thermoset plastic that completely fills all air gaps between mating threads, eliminating fastener back-off caused by severe engine vibration. | Zero Loosening Guarantee: Eliminate costly and dangerous fastener fatigue and subsequent failures. |
Application Steps: Securing Engine Mounting Bolts for Permanent Integrity
Preparation (Safety First): While B72 tolerates minor contamination, for critical engine bolts, cleaning is recommended. Remove heavy grease or oil from the threads using a wire brush and a degreasing solvent. Wipe threads until relatively clean.
Application: Apply a generous, continuous bead of Re-Lok™ B72 onto the leading third of the bolt threads. Ensure the adhesive is spread evenly, but do not coat the first few threads to prevent adhesive pooling.
Assembly: Immediately install the bolt and torque it to the manufacturer’s specified value. Proper torque ensures the metal-to-metal contact required for the anaerobic cure to begin.
Curing Time (Critical): Allow a full 24 hours for the adhesive to reach its maximum high-temperature and high-strength cure. Operating the engine before the full cure time risks compromising the final bond strength.
Stop risking dangerous mechanical failures and secure your structural components with true chemical integrity.
