LOCTITE 638 is a product designed for fastening cylindrical parts, primarily for applications where the gap size can reach up to 0.25 mm. The product cures anaerobically, excluding air between closely fitting metal surfaces, thereby preventing loosening of parts. It can also be used on passive metal surfaces and has excellent polymerization characteristics.
