Loctite 601 is a high-strength anaerobic retaining compound designed for bonding cylindrical fitting parts. Its low viscosity allows it to wick into tight fitting metal surfaces, creating a durable bond that resists loosening from shock and vibration. Ideal for permanent assembly applications
Loctite 601 is a green, single-component anaerobic adhesive developed to secure close-fitting cylindrical parts. It cures in the absence of air and in contact with metal surfaces, forming a rigid bond that distributes stress evenly and prevents fretting and corrosion. With excellent resistance to oils, industrial fluids, and heat, it performs reliably even in harsh environments. It is especially useful for applications that require precision alignment and long-term durability.
