Description
LOCTITE 638 is a one-part, high-strength anaerobic retaining compound designed for bonding close-fitting cylindrical metal components. It is particularly suitable for narrow bond gaps up to 0.25 mm, including slip-fit assemblies. The high-viscosity formulation provides strong retention on a wide range of metals, including passive substrates such as stainless steel, and offers good tolerance to minor surface contamination such as industrial oils. It is commonly used for securing shafts, gears, pulleys, bearings, bushes and similar cylindrical components, helping prevent movement, loosening and fretting.
