► Conical Spring Washers DIN6908 Introduction

Conical spring washers are intended to counteract loosening of such 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.

      Conical spring washers, also called Heavy duty bolting washers, have been specifically developed for high-strength bolts in the strength classes 8.8 – 10.9 as per DIN ISO 898 Part 1 – SAE Grade 5. The loads of Conical Spring Washers have been matched to these bolts and are 70 to 90% of the bolt load in the flat state. They are most effective on axially loaded short bolts where they increase the axial compliance.
