They may not be stripped, have you tried screwing a HS on it?
Looks to me like it might be caused by a lock ring (which have a little tab on them) -

Often forks will have a little space down the threading for spacers and things. do these forks have that on the other side? If not, that may be why they've been sanded down. I'm no expert, but I'd say they're fine.

on a related note:
it's a good idea to throw away the keyed washer of a threaded headset. if you can install and adjust a headset correctly, there is no need for it...there is too much potential to damage/strip the threads. replace it will a small spacer instead.

the flat side is normal but the threads are not clean, you can get them re-cut, saves chewing up your HS threads

those forks are fine. to identify a stripped thread, when you look at the threads, they will appear chewed... there is no 'cleanliness' to the pitch, which is hard to explain. Basically as you look at the first picture you took, the ridges (peaks and troughs) are very uniform they go 'up and down' regularly, just like a sine wave, when a thread is stripped...they aren't, they have had the ridges cut in half or flattened, or just plane 'pulled off' (when a thread is really damaged it can completely detach from the rest of thread, almost coming off in a snake like slither of metal, like a slinky) when this sort of damage appears then it can sometimes be repaired, though it is rather awkward, steel threads are possible (require welding and taps, or a helicoil ) ...though if aluminium (as alot of bike stuff is...it's fucked!) though having said that...there is stuff called lumi weld..which is a fix for non life saving stuff..ie...not a rear hub thread.
/\/\/\/\as you can just about see on here the threads are non uniform and have started to come away from the main body of metal,
on the second picture you can see more damage that is typically stripped\/\/\/\/\/
Having a flat on the thread like that makes no odds to the thread as long as the threads are very clean, (as yours appear to be!)

Hi
Does anyone know of someone in Scotland who can do frame repairs? I need a fork thread rebuilding - it’s worn out! The cost of postage and return from the south is just too great,
Any advice?
Thanks
Hello all I bought a frame and forks off the accursed ebay and on arrival it appears that the threads on the forks are more than a bit stripped! not sure if you can tell from the pictures if the forks can be rescued or if i should bin them and hire a hit squad for the seller. Any input welcome
