Granville Lockthread is a fast-curing, medium-strength anaerobic thread locking compound for bonding and sealing threads and retaining cylindrical parts. It is highly resistant to heat, vibration, water, gases, oils, hydrocarbons, and many other chemicals. The product is removable with normal hand tools. It is ideal for less active materials such as stainless steel and plated parts, and for fasteners between 6-20mm diameters. It locks and seals threaded joints, nuts, screws, and studs with improved oil resistance. This sealant prevents nuts, bolts, and screws from working loose due to vibration or shock, eliminating the need for mechanical locking devices. It also seals threads against leaks or corrosion and seals pipework joints on petrol, oil, and hydraulic systems.
