Nuts!!!

[ayjay]

CP18 needs a 7/16" captive nut. Is that spanner size (which seems a bit small)
or a thread size?And why not metric?
Also was I right in thinking that that the M8 for the roll cage bolts equate to 13mm spanner size ?

Grateful for any help -nearly ready to weld up the chassis - does any one think smooth hammmerite might do a decent paint job( I've got a big tin of it in the shed)

Thanks
