Threadlocker Adhesive – Stop Screws from Loosening for Good
Vibration, heat, and mechanical stress cause fasteners to loosen over time. This anaerobic threadlocker adhesive cures in the absence of air to create a powerful, permanent bond between metal threads — preventing loosening, leaks, and corrosion. Available in 243 medium strength (removable) and 271 high strength (permanent) formulas.
Formula Guide
243 Medium Strength – Locks threads securely while remaining removable with standard hand tools. Ideal for bolts and fasteners that may need future adjustment.
271 High Strength – Permanent locking for critical fasteners. Requires heat or press tools for removal. Best for heavy-duty mechanical and automotive applications.
Key Features
Anaerobic Formula – Cures only between metal surfaces in the absence of air — no mess, no waste
High-Temperature Resistant – Maintains bond integrity under heat and vibration
Anti-Loosening Sealant – Prevents fastener back-out caused by vibration and thermal cycling
Multi-Purpose – Works on steel, stainless steel, brass, and most metal alloys
Quick-Setting – Fast fixture time for efficient assembly
