Powerful thread locker for large fasteners, 5-pack
✔️ High-strength anaerobic sealant for large bolts, resists vibration

Red high-strength thread locker is a single-component anaerobic formula that cures in the absence of air between close-fitting metal surfaces to form a permanent lock. It’s ideal for heavy-duty fasteners in automotive, heavy equipment, and industrial machinery where loosening is unacceptable.
