| Re: Frank's KVA Build Frank, If you wish to make your bolts vibration proof & sort of self locking--- drill a hole about 3mm dia x 3mm deep in the thread portion that sits in the welded/captive nut, press a short piece of hard nylon rod into this hole and trim off slightly above thread tops and fit to car. The nylon acts as a semi self locking aid without causing any thread deformation etc.
