Can 14mm hexes fit the 12mm hexes on a pede?

[rawfuls]

Well, I'm thinking about selling some tires to a fella, but he's unsure if they'll fit his pede..

Anyways, they're regular bowties m3 from Pro Line, with ProLine Rims.... They have 14mm hexes, but he was asking if there was anyway to get them to fit his pede.

I also have some 40series that he's very interest in as well, but they're 17mm, comes with 17->14mm adapters... Any help?
