Detailed Information

The surface of the spring washer and of the safety ring must be smooth and free from scale and burr.

The spring washers must be coiled with constant pitch and without any kinks (with the exception of the barbing of the ends). The ends of the spring washer which bite into the parent material must be sharp. The outer edges are generally square, but may also be lightly rounded. The bevelled ends must not expand the spring washer when the latter is compressed without the safety ring. The spring washers must not drop out of the safety ring.
