LOCTITE 263 THREADLOCKER HIGH 10ML

Lock fasteners permanently with Loctite® 263, the trusted high-strength red threadlocker designed for critical assemblies exposed to extreme vibration, shock, and stress. This advanced dual-cure acrylic formula provides permanent locking and sealing of threaded fasteners, preventing loosening and leakage in even the harshest operating environments.

Loctite 263 cures between metal surfaces to form a vibration-proof bond and is effective on both active metals (like brass and copper) and passive substrates (such as stainless steel and plated surfaces). Its oil-tolerant formulation allows reliable curing even on lightly contaminated threads, ensuring dependable results in every application.

Perfect for heavy-duty equipment, motor housings, gearboxes, presses, and agricultural machinery, Loctite 263 offers robust strength, high temperature resistance, and long-term performance. Once cured, removal requires localized heat and hand tools, making it ideal for permanent assemblies where reliability is paramount.
