I don't know the size off the top of my head, but I ordered a set of miniature wrenches from 5/16" down to 5/64" and one of them fit. I think it would be hard to find just one wrench in the size you need.the king lock nut for tenor, what size of wrench does this need pls? i assume it would not be a metric size...
thanks in advance for any info
Your local auto parts store will sell a set of small wrenches, calling them "ignition wrenches", for short money.The size is 3/16". Sometimes the corners of the nuts get damaged by using an adjustable wrench, so the correct 3/16" wrench feels tight.
If you look on ebay, occasionally you will see an individual 3/16" wrench, new or used, for a reasonable price.
