LOCTITE® 263

Features and Benefits

Dual cure, acrylic dimethacrylate ester fluorescent threadlocker designed for the permanent locking and sealing of threaded fasteners.
LOCTITE® 263 is a red, high-strength, primerless threadlocker for permanently locking and sealing bolts, nuts and studs to prevent loosening due to vibration. It works on all metals, including passive substrates such as stainless steel, aluminum and plated surfaces without the use of primer. Suitable for use on most oil-coated, “as-received” fasteners without cleaning.
  • Particularly suited for heavy duty applications such as studs into motor housings where high strength is required
  • Prevents loosening and leakage from shock and vibration
  • Designed for the permanent locking and sealing of threaded fasteners
  • Provides robust curing performance
  • Offers high temperature performance and oil tolerance
