LOCTITE® 248 Threadlocker
Features and Benefits
Easy-to-apply, semi-solid stick for locking and sealing threaded assemblies - ideal for vertical and overhead applications. Medium strength, removable with hand tools.
LOCTITE® 248 is a blue, general purpose threadlocker that provides a medium-strength bond in a convenient stick format for no-drip, no-mess applications. It locks and seals bolts, nuts and studs to prevent loosening due to vibration, and works on all metals, including passive substrates such as stainless steel, aluminum and plated surfaces without the need for a primer. Suitable for use on most oil-coated, "as-received" fasteners without cleaning.
