With Loctite 222, you reliably secure and seal small threaded fasteners with complete control. This purple, low-strength liquid threadlocker is specially designed for fasteners up to 1/4" and prevents adjustment screws or countersunk screws from backing out under heavy vibration and mechanical shocks. By curing anaerobically between close-fitting metal surfaces, it also seals threads against moisture ingress, leakage, and corrosion. It is ideal for lower-strength metals such as aluminum or brass, allowing you to disassemble components effortlessly with standard hand tools without shearing the fasteners. This 250 ml bottle provides ample capacity for precise, dependable assembly and maintenance work.
