Chainsaws and trimmers subject their fasteners to some of the harshest conditions in any machinery: extreme, continuous high-frequency vibration from the small 2-stroke engine, constant exposure to fuel/oil mixtures, and high torque loadson clutch and bar mounting points. A loosened bolt here can lead to immediate loss of power, component separation (like the bar or clutch), and is a significant safety hazard. However, these tools require frequent maintenance and disassembly.
Don’t let engine vibration loosen your critical fasteners; secure them while maintaining serviceability.
INCURE Re-Lok™ B43 Blue Standard Duty Threadlocking Adhesive
For securing fasteners on high-vibration power tools—including engine mounts, handle bolts, clutch covers, and bar studs—a balance of high security and disassembly is crucial. The INCURE Re-Lok™ B43 Blue is the ideal solution, providing excellent anti-vibration security that is highly resistant to gasoline and oil, yet can be removed with standard wrench pressure.
| Feature & Benefit | Technical Insight for Power Tool Bolts | Conversion Value |
| Medium Strength (Standard Duty) | Provides a secure lock for fasteners up to M20, preventing loosening from severe vibration, while still allowing for removal with standard hand tools. | Field Serviceable: Lock down the component for work, but permit hassle-free cleaning and repair access. |
| Fuel & Oil Resistance | Exhibits strong chemical resistance to gasoline, bar oil, 2-stroke mix, and common cleaning solvents used in power equipment maintenance. | Engine Ready: Ensures the chemical lock remains robust despite exposure to engine fluids and high-contamination areas. |
| High Vibration Dampening | Cures into a solid plastic that fills the microscopic gaps, effectively neutralizing the intense, high-frequency “buzz” of 2-stroke engines. | Stop the Rattle: Eliminate creep and fastener back-out, maintaining safe torque on structural components. |
| Fast Curing Speed | Reaches initial cure in 20 minutes, minimizing assembly time and allowing the tool to be quickly returned to service. | Maximize Uptime: Accelerate your repair process with quick-curing, robust component security. |
Application Steps: Securing Chainsaw/Trimmer Bolts for High-Vibration Use
Preparation (Key to Success): Clean the threads of both the bolts and the receiving threads (e.g., in the crankcase, handle) thoroughly. Use a strong degreasing solvent to remove all residual oil and fuel film, ensuring surfaces are clean and dry.
Application: Apply a continuous, thin bead of Re-Lok™ B43 Blue to the leading three-quarters of the bolt threads. For exposed bolts (like handle mounts), ensure the coverage is thorough.
Assembly: Install the component. Torque all fasteners evenly to the manufacturer’s specified value to ensure proper clamping pressure and initiation of the anaerobic cure.
Curing Time (Critical): Allow a minimum of 24 hours for the adhesive to achieve its maximum strength and anti-vibration resistance before operating the tool under full engine load.
Stop risking dangerous mechanical failures and secure your power equipment with dependable chemical integrity.
