That's good stuff ! http://www.ebay.com.au/sch/i.html?_...ers&rt=nc&LH_PrefLoc=2&_trksid=p2045573.m1684 I try to use the serrated flange nut's where i can, sort of the same principal but without the extra lock
Good idea. Could see many uses for it in engineering and building. Must be one severe test vibration machine. In all the years I have worked with Nyloc nuts have not seen one undo like that. Would not want to use on aluminium, would 'chew' into the parent metal and if used over a plain washer would loose the locking effect.
