Fasto A143 is a general purpose, medium-high strength, very fast curing and high performance thixotropic anaerobic threadlocker. Fasto A143 is formulated to lock all metric and imperial nuts and bolts, preventing vibration loosening and leakage through the threads. A143 is oil tolerant, so it will bond ‘as received’ parts, but best results are obtained with clean substrates. The thixotropic nature of the product prevents run off, dripping and migration after assembly. The product cures when confined in the absence of air on close-fitting metal surfaces. TYPICAL APPLICATIONS Fasto A143 is suitable for most medium and coarse threaded screws, nuts and bolts. Fasto A143 is typically used on mounting bolts, housing screws, cap screw of industrial static & dynamic machines. Fasto A143 can also be used for threadlocking applications of automobile assemblies. A143 prevents corrosion of assembled parts
