This standard is included in DIN Handbook 10. Specifies requirements for screw and washer assemblies consisting of an M 2,5 to M 12 screw with flat bearing face, assigned to property classes 8.8 up to and including 10.9, and a captive conical spring washer. Wave spring washers are intended to counteract loosening of bolted connections (e.g. as a result of setting) (cf. DIN 267 Part 26). They do not effectively prevent loosening of the connection under varying radial load and are thus designed for use with short screws predominantly subject to thrust.
