Product Description
LOCTITE® 2701 is a high-strength anaerobic threadlocking adhesive designed for the permanent locking and sealing of threaded metal fasteners. The one-component acrylic formulation cures in the absence of air between closely fitting metal surfaces, preventing loosening and leakage caused by shock and vibration. LOCTITE 2701 is particularly well suited for inactive metal substrates such as stainless steel and plated metals, and for applications requiring maximum resistance to hot oils. The low-viscosity adhesive penetrates threads efficiently while providing strong locking performance, excellent chemical resistance and long-term durability in demanding industrial environments.
Key Features & Benefits
- High-strength threadlocker for permanent fastener locking and sealing.
- Designed for inactive metals including stainless steel and plated surfaces.
- Excellent resistance to hot oils and industrial fluids.
- Prevents loosening caused by vibration, shock and dynamic loading.
- Low-viscosity formulation promotes efficient thread penetration.
- One-component anaerobic adhesive requiring no mixing.
- Fluorescent under UV light for inspection and quality control.
Recommended Applications
- Permanent locking of threaded fasteners.
- Sealing threaded assemblies against leakage.
- Fasteners subjected to shock and vibration.
- Assemblies operating in hot-oil environments.
- Industrial machinery, pumps, gearboxes and maintenance applications.
