I've gotta remove a (CJ) propshaft thats held on by those poxy little Bi-Hex headed bolts both ends.
Non of my spanners seem to fit, tho it looks like a 5/16" bi hex spanner would fit, mine don't seem to want to.
If I could find a spare one ( I must have one somewhere, just don't know where) I could take it to an engineers merchant and get sorted with something.
As it is I'd have to toss the complete axle on the trade counter.
Anyone got a clue what size they are, I'm fed up of grinding their heads or wacking f**k out of them with a hammer and chisel.

all my prop bolts were metric
-
All the ones I've come across are 8mm double hex.
-
These have a 1/4" UNF thread on 'em and the T/C and Axle drive flanges are theaded to take 'em.
They're on the flat strap type UJ retainers and are a PITA!
U bolt types seem easier to work with and are 5/16" UNF thread so I suspect they are stronger, but this bugger aint got 'em.

Actually, I never tried any metric spanners, 'cos I knew they are UNF fixings, but I'll give it a try tomorrow.

5/16 A/F= .3125"
8mm A/F= .315"
dont think you will notice much difference
will be better with a 6 sided socket for sure if you can get one on
-
for the TJ i use a 1/4 drive 6 sided 8mm socket IIRC

Remember these are a one use bolt!!!

Cheers, I didn't know that.
Maybe I should actually spend some time reading all those expensive manuals I bought.
I guess they guy who nailed the Yellow Perril (CJ7 diesel) together before I bought it didn't know that either, 'cos there were LOOSE cap head bolts holding the UJs on when I got it.

Isn't 'use once bolt' dealer speak charge the sucker extra?
-
Remember these are a one use bolt!!!
Doesn't mention anything about replacing them in the FSM. I'm pretty sure it would state to replace them if they were.

*sigh* young Jedi much to learn one has...
-
Remember these are a one use bolt!!!
are these stretch bolts then ?
use some thread lock and no problems.
-
After all that I found a 5/16" bi-hex spanner that dropped straight on them 100% good fit.
Other 5/16 spanners I got won't fit or slip.
Moral of the story: stop buying cheapo spanners from market stalls.
