200tdi Turbo question

[92a]

Sorry if this seems a bit silly but are the bolts that hold the plates that in turn hold the turbo cartridge in place actually M8 or an imperial thread ? I used a 1/2 AF open ended spanner as it was a better fit and it’s got me wondering? Thanks Angus

M8.  Most likely 12mm heads.  12mm heads are common for M8.

The 8.8 stamped on the head suggests metric. Mine were 13mm heads, which is the ‘standard’ size for an M8 fixing.

I also used a 1/2” spanner as it was a tighter fit on the slightly corroded heads.

Well....  It is not standard everywhere.  Japanese standard is 12 mm. You must never have seen a Japanese car.

It’s the ‘standard’ size on a Land Rover. And yes there are numerous M8 fixings with 10mm heads on the vehicle before it’s pointed out 

Fully aware of the Japanese standards thank you.

It's fine, this is usual. Red90 is a very clever bloke, often right. But he lacks a certain subtly when dealing with human kind. I believe it's because he is an 'Engineer'. At work we don't let 'Engineers' out alone, nor do we leave them with the crayons or wipe board markers; and they are just civil engineers, the highest up the evolutionary development scale...
