LOCTITE® 262™
LOCTITE® 262™ is a red, high-strength anaerobic adhesive formulated for the permanent locking of metal threaded fasteners up to M25. It cures in the absence of air and resists shock, vibration, and mild oil contamination.
LOCTITE® 262™ Features:
- High strength and general-purpose threadlocking
- Thixotropic for reduced migration
- Fluorescent under UV light for inspection
- Resistant to vibration and light oil contamination
LOCTITE® 262™ Applications:
- Permanent threadlocking of large bolts and studs
