Need to chase some hub axle threads smooshed by my mountain bike's rear
dropouts. Can't spin the locknuts or cones off to service the bearings. The
hub's Deore XT, circa 2001. From this handy dandy chart on Sheldon Brown's
site,

It looks like 10mm diameter and 1mm pitch. Just don't want to go purchasing
the wrong die and destroying the threads entirely.

Hacksaw off the damaged section(s) close to the locknuts, remove the
locknuts and cones then buy a new axle? Might work out cheaper and the
job will be a good 'un. A new 146mm x M10 x 1mm axle will cost you the
princely sum of $8.75 from The Third Hand.
