When you need to lock and seal fine threaded nuts, bolts and studs in legacy applications where certification to Mil-S-22473E Grade C is required, choose LOCTITE® Grade C (84). This blue, low viscosity, medium strength anaerobic curing adhesive cures in the absence of air and presence of metal. It fluoresces under UV light – great for quality control.
