Anyone know what size the head bolt is for an OS .25?

Thanks
Paul

I always go to m y local ACE Hardware store to get metric socket head screws for my OS engines. I just start thru the bins until I find what I need. They're getting used to me carrying in engines. DOC Holliday

I could be wrong but I believe it is an M3 Paul. At least it's a place to start. I know the LA is an M3.

FP has six head bolts, same thread as the cover plate, just longer. 2.5 mm

LA has four head bolts, 3mm

Tower parts, note these for the FP are the dreaded JIS "quasi-phillips" heads, not allen socket!

Tower gives you the screw sizes. Buy socket head screws from Micro Fasteners. 7mm long is a bit scarce but it's easy to cut down something longer for the backplate.

Cheers, Geoff
