- Slow Cure Profile
Product Description
LOCTITE® 2047™ is a one-component anaerobic threadlocker formulated for high-strength locking of threaded fasteners while providing enhanced lubricity. Designed for assemblies requiring reliable resistance to loosening and leakage caused by shock and vibration, the product cures when confined between closely fitting metal surfaces in the absence of air. Its specialized lubricant additives provide lubricity comparable to conventional metal-free anti-seize products while maintaining threadlocking performance. LOCTITE 2047 features a deliberately slow cure profile that allows multiple fasteners to be torqued in large assemblies before curing begins, making it particularly suitable for large, highly torqued bolt applications where assembly-generated heat could otherwise cause premature curing.
Key Features & Benefits
- High-strength anaerobic threadlocker for metal threaded fasteners.
- Contains lubricant additives that provide lubricity comparable to metal-free anti-seize compounds.
- Prevents loosening and leakage caused by shock and vibration.
- One-component formulation requiring no mixing before use.
- Slow cure profile allows sequential torquing of multiple bolts before cure initiation.
- Suitable for large, highly torqued fasteners where assembly heat may otherwise induce premature cure.
Recommended Applications
- High-strength threadlocking of nuts and bolts.
- Threaded assemblies exposed to vibration and shock loading.
- Large-diameter and highly torqued bolted assemblies.
- Thread sealing applications requiring leak prevention.
- Industrial maintenance, assembly and heavy equipment fastening.
