AN ANTI-VIBRATION NUT

The Lester anti-vibration nut has successfully been tested on railway permanent way over a period of several years. It is free running when first screwed on to the bolt, but on tightening the nut, the conical discs tend to flatten, until the threads cut in them. A further feature of the Lester nut is its ability to be unscrewed without damage and the fact that it dispenses with washers. Since first being used, the nuts are estimated to have carried some 36 million tons of traffic at speeds of 40-45 m.p.h., without requiring retightening.
