LOCTITE 263 THREADLOCKER HIGH 50ML

When only a permanent hold will do, Loctite® 263 delivers unmatched strength and reliability for critical fastener locking and sealing applications. This high-strength red threadlocker is designed for permanent assembly, preventing bolts, nuts, and studs from loosening due to vibration, shock, or thermal cycling.

Formulated for use on both active metals (such as brass and copper) and passive substrates (like stainless steel and plated surfaces), Loctite 263 provides robust curing performance, even on slightly oily or contaminated threads. It’s ideal for heavy-duty machinery, motor housings, gear assemblies, and other high-load environments where fasteners must remain secure under extreme conditions.

Once cured, Loctite 263 creates a tough, vibration-proof bond that resists heat, chemicals, and corrosion — offering long-term dependability in industrial, automotive, agricultural, and manufacturing applications.
