Loctite 263 High Strength Threadlocker
High-Strength Permanent Locking Solution
LOCTITE® 263 is a red, high strength, primerless threadlocker specifically engineered for permanent locking and sealing of bolts, nuts and studs. This advanced anaerobic adhesive prevents loosening due to vibration and provides reliable fastener security in demanding applications.
Key Features
- High Strength Formula: Delivers permanent locking strength for critical fastener applications
- Primerless Application: Works on all metals without primer, including passive substrates such as stainless steel, aluminum and plated surfaces
- Oil Tolerant: Suitable for use on most oil-coated, 'as-received' fasteners without cleaning
- Temperature Resistant: Operates continuously from -55°C to +150°C (-67°F to +302°F)
- Dual Cure Technology: Acrylic dimethacrylate ester fluorescent formula for reliable curing
- Surface Insensitive: Effective on both active metals (brass, copper) and passive substrates
Applications
- Heavy duty applications requiring high strength
- Motor housing studs and bolts
- Transmission components
- Automotive and industrial fasteners
- Applications subject to shock and vibration
