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. Cures through most corrosion prevention oils and cutting fluids on "as-received" fasteners without aggressive cleaning.
