Product Description
LOCTITE® 294™ is a medium-to-high-strength anaerobic threadlocking adhesive designed for the locking and sealing of pre-assembled threaded fasteners. Its low-viscosity formulation enables capillary action, allowing the adhesive to wick into engaged threads without requiring disassembly before application. The product cures when confined between closely fitting metal surfaces in the absence of air, preventing loosening and leakage caused by vibration, shock and dynamic loading. LOCTITE 294 also performs effectively on oil-coated fasteners, making it particularly suitable for maintenance, repair and production environments where disassembly is impractical.
Key Features & Benefits
- Wicking-grade threadlocker for post-assembly application.
- Low-viscosity formulation penetrates threads through capillary action.
- Medium to high locking strength for threaded fasteners.
- Prevents loosening caused by vibration, shock and dynamic loads.
- Seals threaded assemblies against leakage.
- Provides effective performance on oil-coated fasteners.
- Fluorescent under UV light for inspection and quality control.
Recommended Applications
- Post-assembly threadlocking of preassembled fasteners.
- Maintenance and repair operations.
- Locking of set screws and adjustment screws.
- Sealing of threaded assemblies against leakage.
- Equipment exposed to vibration and shock loading.
