　　LOCTITE® 263™ is designed for the permanent locking and

　　sealing of threaded fasteners. The product cures when

　　confined in the absence of air between close fitting metal

　　surfaces and prevents loosening and leakage from shock and

　　vibration. LOCTITE® 263™ is particularly suited for heavy duty

　　applications such as studs into motor housings, nuts onto studs

　　in pump housings and other fasteners where high strength is

　　required. LOCTITE® 263™ provides robust curing

　　performance. It not only works on active metals (e.g. brass,

　　copper) but also on passive substrates such as stainless steel

　　and plated surfaces. The product offers high temperature

　　performance and oil tolerance. It tolerates minor surface

　　contaminations from various oils, such as cutting, lubrication,

　　anti-corrosion and protection fluids.
