Spring Lock Washers with Safety Ring
|Publication Date:||1 October 1987|
Scope and field of application
Spring lock washers covered in this standard are deemed to be spring washers designed for use for bolt/nut assemblies involving bolts of property class 5.8 or less 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 bolts predominantly subject to thrust.
