268xp head bolt size.

[Toad]

Afternoon. Trying to strip down a 268xp which appears to have had something heavy on top of it, like a tree or a tractor and chuck the damaged bits in the scrap bin. 

 

Might anyone know what size the head bolts are? I've a feeling they are 4.5mm hex, but it seems an odd size. 

 

Might anyone want a piston, crank, oil pump, clutch and flywheel when I get it apart?

Imperial set of keys you need can't remember size.

I think its a 3/16 AF imperial allen wrench needed ,  think its its a coarse pitch thread  which is why its imperial /SAE/AF  hex head  i did take my pals  268 apart a couple of years ago 5mm didnt fit and the 4 was way loose , so went to toolbox and the imperial ones fitted  but may be wrong as i did tear apart a lot of saws and think it was that one that was oddball size , , i,m not home now so cant know the one i used, but pretty sure is a 3/16
