Small components found in, for example, instruments and switches may be locked by the application of Shellac, Araldite, Loctite, or similar materials. Shellac and Loctite are usually applied to the threads of nuts, x bolts, screws and studs and the components are assembled while still wet. The parts should be free from grease to achieve maximum strength. Araldite is applied to the outside of the nut face and the protruding screw thread, after tightening. Araldite is an adhesive which hardens, after mixing, within a specified time period.
