With Loctite 601, you create a permanent, high-strength bond across close-fitting cylindrical metal assemblies. Thanks to its low-viscosity liquid formula, this retaining compound effortlessly fills narrow diametrical gaps up to 0.1 mm between shafts, bearings, bushings, and housings. Curing anaerobically in the absence of air between metal surfaces, it withstands severe vibration, dynamic shock loads, and temperatures ranging from -55 °C to +150 °C. You effectively prevent fretting corrosion, loosening, and leakage without relying on high machining tolerances. The handy 50 ml bottle delivers controlled application for precision assembly and demanding machinery maintenance.
