Tap size?

[vapingcarper]

Hi all not sure if this is in the right section so please feel free to move if not. Right I'm wanting to make a mod / atty stand and was wondering what tap would be needed to thread my aluminium block so I can screw I'm atty's onto it?

This will be my 1st attempt so will post some pics up once completed.

Thanks for that mate I'll have a search around at work to see if I can get hold of a 7mm tap and give it a go.

From what I've seen it's not a very common thread size. I bought the tap on ebay for £9
