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 fastener loosening and leakage from shock and vibration
- Permanent locking and sealing of threaded fasteners - removable with heat
- Requires heat for disassembly
- Offers high temperature performance (up to 360°F) and oil tolerance

Features and Benefits
- Prevents loosening and leakage from shock & vibration: It occupies all gaps between the mating threads and cures into a hard thermoset plastic that strengthens the assembly against self-loosening by adding approximately 40% to the normal loosening torque.
- High strength: Designed for permanent applications which must not come loose. Needs localized heating to disassemble.
- Works well on all metal substrates even passive ones like stainless steel and plated surfaces.
- Fluorescent: It has a characteristic red colour that fluoresces under UV light. This helps during service to detect as to whether or not the product had been applied.
