Monaro engine cover nuts? what size thread.

[Lincsls1]

Hi.
Anyone know what size the nuts are holding the engine covers on?
Cheers...

ETA:
Definitely an M5 thread, for anyone that might want to know in the future.

it looks like a 10mm , but it’s a capped one which is unusual

6mm thread so 10mm spanner

My LS1 is M5

they are an odd nut.. m5 thread but a domed nut that a 10mm spanner fits

maybe a visit to rockauto website , even if more is paid in p and p than the cost of the nuts , or a car breaker

I've ordered some M5 domed nyloc stainless nuts and some M5 stainless penny washers.
