Description
Threadlocker BLUE (9243) is a medium-strength anaerobic adhesive designed for sealing and locking threaded fasteners that may require future disassembly. This single-component, thixotropic, acrylic-based threadlocker cures in the absence of air when confined between metal surfaces. It prevents loosening caused by vibration and shock, while still allowing removal with standard hand tools when maintenance is required.

Product Highlights
- Medium-strength formulation for applications requiring future disassembly
- Prevents loosening caused by vibration, shock, and mechanical stress
- Anaerobic curing activates between metal threads for secure fastening
- Thixotropic nature prevents running and ensures controlled application
- Ideal for bolts, screws, nuts, and assemblies needing maintenance access
Technical Specifications
| Property | Specification |
|---|---|
| Chemical Base | Acrylic anaerobic adhesive |
| Strength Level | Medium strength |
| Curing Method | Anaerobic (cures without air between metal parts) |
| Viscosity | Thixotropic (non-runny, controlled application) |
| Typical Applications | Fasteners requiring occasional servicing or disassembly |
| Temperature Resistance | Typical resistance up to 150°C (varies by substrate) |
Application Instructions
- Clean all threaded surfaces to remove oil, dirt, or contaminants.
- Apply a small amount of Threadlocker BLUE to the male threads.
- Assemble and tighten the fastener to the required torque.
- Allow adequate curing time for full strength before operating equipment.
Coverage Calculator
- One 50 mL bottle supports multiple medium-sized threaded assemblies; actual usage depends on bolt diameter and thread length.
Suitable Applications
- Automotive maintenance and general vehicle repair
- Industrial machinery requiring periodic servicing
- Metalworking and fabrication
- Equipment that experiences moderate vibration
Compatibility & Limitations
- Compatible with most metal fasteners and threaded assemblies
- Not suitable for plastic threads or assemblies requiring very low-strength bonding
- Provides secure locking but still allows disassembly with standard tools
Safety & Handling
- Avoid contact with skin and eyes; wash thoroughly after handling
- Use in a well-ventilated workspace
- Store tightly closed in a cool, dry area
- Keep out of reach of children
Frequently Asked Questions
It is used to seal and lock threaded fasteners while still allowing future disassembly.
Yes, it can be removed easily using standard hand tools.
No, it cures anaerobically when confined between metal surfaces.
