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 without primer, including passive substrates such as stainless steel, aluminum and plated surfaces. Suitable for use on most oil-coated, 'as-received' fasteners without cleaning.
Prevents fastener loosening on vibrating assemblies, e.g. pumps, gear boxes or presses
Works on all metals, including passive substrates
Suitable for use on most oil-coated, 'as-received' fasteners without cleaning
Can be disassembled with ordinary hand tools for easy service and maintenance
NSF/ANSI 61 certified
Ideal 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
