Drive shaft bolts are arguably some of the most critical fasteners on any drivetrain. They operate under a triple threat of extreme demands: relentless rotational torque, high-frequency driveline vibration, and severe shock loads during vehicle launch or gear engagement. A drive shaft bolt failure is not just a breakdown; it’s a high-speed safety risk that can lead to catastrophic component separation.
Don’t trust traditional fasteners alone; secure the power transfer with the toughest chemical lock.
INCURE Re-Lok™ B72 Red Heavy Duty Threadlocking Adhesive
For securing structural, high-torque drivetrain components like drive shaft flanges, the fastener must be virtually permanent. The INCURE Re-Lok™ B72 Red is a high-strength, high-temperature anaerobic adhesive designed to withstand the highest levels of torque and shock loads encountered in the driveline.
| Feature & Benefit | Technical Insight for Drive Shaft Bolts | Conversion Value |
| High Strength, Permanent Lock | Provides the maximum holding power available, securing structural bolts up to M36 against separation from intense rotational and braking forces. | Maximum Security: Achieve a permanent bond that prevents rotation and failure in critical, high-speed applications. |
| Extreme Vibration Dampening | Cures into a rigid plastic that fills all microscopic gaps, effectively cementing the fastener in place to eliminate loosening caused by constant driveline vibration. | Stop the Shake: Eliminate back-out and fastener fatigue, extending the service life of your drivetrain components. |
| High Thermal Endurance | Withstands continuous operating temperatures up to 230°C, maintaining its strength even when exposed to high heat from the differential or surrounding exhaust. | Heat-Proof Confidence: Ensure the lock remains stable and secure under peak operational thermal load. |
| Contaminant Tolerance | Designed to cure quickly and reliably even if surfaces are not perfectly cleaned, providing durability in a typically contaminated undercarriage environment. | Reliable Results: Get dependable performance without requiring extensive and time-consuming component preparation. |
Application Steps: Securing Drive Shaft Bolts for Maximum Driveline Safety
Preparation (Mandatory): For maximum safety on a structural fastener, clean the bolt threads and the receiving threads (flange or yoke) thoroughly using a wire brush and a heavy-duty degreasing solvent. Surfaces must be dry and free of excessive grease.
Application: Apply a continuous, liberal bead of Re-Lok™ B72 Red around the leading three-quarters of the bolt threads. For best results, ensure the adhesive is applied to both the bolt and the mating blind hole.
Assembly: Immediately install the bolts. Torque all fasteners evenly to the manufacturer’s specified value to ensure proper component seating and optimal anaerobic cure initiation.
Curing Time (Critical): Allow a full 24 hours for the adhesive to achieve its maximum high-strength and thermal-resistant cure. The vehicle must not be operated under load before the full cure time is complete.
Stop risking catastrophic mechanical failures and secure your structural components with the toughest chemical integrity.
