I have been working on hex head valve gear hangar bolts & found my current nut driver is not suitable as the inner face has too much lead in chamfer.
Before it can get a grip on the 3mm hex head bolt it hits the valve gear behind the bolt head.
Because it has to get on to a hex head bolt that has a flange very close to it I need a 'thin wall/non chamfered' 3mm nut driver.
Anyone know where such an item is available?
Or, alternatively, what do others use to unbolt valve gear hex head bolts??
Thanks

Maybe you can grind your nut driver past the chamfer,or get an allen bolt with a 3mm hex hole in it?
