Serrated lock washers are primarily intended to establish electric contact in cases where the screwed parts are coated with non conducting lacquer and similar coatings. If such washers together with bolts and nuts of low property classes are used to prevent unscrewing, then the suitability for this purpose shall be proved in each case.

Circlips are made from carbon spring steel strips or bars serve as radial spring fasteners for positioning and retaining components in assembly. Normally, the circlips are either axially assembled (either over shafts or inside bores) or radially assembled over shafts.

Belleville spring washers type ‘A’ can be used in most light metal assemblies to provide a useful elastic spring action proportionately high with respect to the washer’s outer diameter. They can be flattened out completely when tightened, with out effect on their elasticity. Also used in certain assemblies with out effect on their elasticity. Also used in certain assemblies with a view to compensating any axial play. Belleville spring washers type ‘B’can be used with all grades of materials of bolts or screws, as well as the torques applied therewith.
