Derailleur hanger bolt, c20mm ?

[LittleSkink]

I have a DMR Singlespeed tensioner that isnt holding as securely as I need for rough riding, the derailleur hanger thread is about 20 years old so I am reluctant to tighten too much

Looking for an M10mm 1mm pitch bolt with about 20mm of thread (hanger + DMR body + nyloc nut). Plan is to bolt up from behind and secure the nut from outside to minimise stress on hanger thread

Anyone point me in the right direction? ebay has some extra fine M10 nuts but can find any suitable bolts

Or just use a normal but or a half nut.
Or two half nuts if you want a locknut.

Re:

Same thread as a shimano rear hub axle if I remember rightly. Will some narrow locknuts do the trick?

Re: Deraileur hanger bolt, 15mm +?

bumping this as I still need a bolt with 20mm of thread - anyone point me in the right direction, nuts are easy enough - bolts dont seem to be

Pref hex head over allen key as I dont have easy access to bolt once installed
