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

When a drawing states a thread size it means thread not the spanner...so 7\16 it is and m8....depends what fitting used as some jap stuff use small heads and could well be a 12mm across flats spanner

7/16" UNF thread

Motoring indusry stardard thread used in seatbelt bolts ( Exept for most Jap stuff )

Yep, as said 7/16 unf. It's a finer thread than an m8, you'll see the difference when you get them.
