#Salient Features of External Circlips
Scope and Field of Application Disc Spring : Conical spring washers covered in this standard are deemed to be spring washers designed for the use for bolt/nut assemblies involving bolts of property classes 8.8 to10.9 as specified in ISO 898 part 1. They are intended to counteract the effect of setting which results in bolt/nut assemblies working loose (see DIN 267 part 26). They do not effectively prevent loosening of the assembly under varying radial load and are designed for use with short bolt predominantly subject to thrust.
