Elliot Progress 2G

[Alan Frith]

Could anyone tell me what size allen key fits the gearbox oil filler plug on an Elliot Progress 2g Bench drill?
I assume it is a Whitworth but would like the exact size please.

Many Thanks.

wether its whit worth,bsf,unf,unc,the allen key will always be an imperial one,suggest you measure with a vernier.

Drain is 1/4 and filler is 5/16 in AF

Allen keys can be imperial or metric
