This low-strength thread locker locks and seals small fasteners under 6.35 mm (1/4″”) in diameter. It prevents loosening from shock and vibration and is removable with hand tools.
If you’re working with small-diameter screws made of low-strength metals (e.g., aluminum or brass), try LOCTITE® 222. It is ideal for low-strength thread locking of adjustment screws, countersunk head screws, and set screws; on collars, pulleys, tool holders, and controllers. It works on most metals without primer, including passive substrates such as stainless steel, aluminum, and plated surfaces. It also cures through light coatings of corrosion prevention oils without having to clean the parts.
