• Ideal for shafts, gears, pulleys and similar cylindrical parts
• High strength on all metals, including passive (e.g. stainless steel)
• High temperature resistance
• Fluorescent under UV for quality control

High strength, general purpose bonding of cylindrical parts

Designed for bonding cylindrical fitting parts, particularly with narrow bond gaps up to 0.25mm (0.01"). Great for a fast cure on all metals, including passive substrates like stainless steel.

For a retaining compound offering high strength on all metals, including passive substrates, try LOCTITE® 638. You can expect high temperature performance and good oil tolerance, a fixture time of just four minutes, and gap fill of 0.006" to 0.01" (0.15 mm to 0.25 mm). It even tolerates minor surface contaminants, including industrial oils. A high viscosity product, it’s ideal for shafts, gears, pulleys, and similar cylindrical parts. Operating temperature is -65°F to 355°F (-55°C to 180°C).
