BMX Sprocket/Chainring securing pin measurement

[Flowta]

To the BMX riders out there.

 

What is the measurement of the locating pin to the centre of the axle for a 3 piece cranks set?

 

Been googling with all my might but can't find anything out there. Haven't been able to get to the bike shop to measure up there either.

 

Thanks

normally 3.5cm from centre of spindle to centre of pin hole. pin hole is oval though so give or take 2mm. Some cranks are not that well checked in QC and can vary quite abit.
