Can someone please confirm if they are 7/16 AF?

Sorry, what I should have asked, are the bolt heads 7/16 AF?

That's way too small - I think they are 9/16

I seem to remember 11mm being the best fit.

The Essex pre-dates metric bolts, this should do the job....

Looks like 7/16 - and with a head of 11/16

That's not a big end.

Now you're being pinickity


Op, can I ask why you're asking? Do you have the sump off and struggling to get a socket to fit or are you ensuring you have the correct tools available for when it does come off?

Very true and well spotted. Very long day yesterday

I should clarify that by 11mm I mean the head size, as I'm sure it was a slightly snugger fit.

The bolt itself is obviously imperial, so 7/16.
