Those threads are not Imperial. That bridge is made in Taiwan or Korea, by Ping, for Fender, and the threads are M3 as are the threads in the MIM Standard Strat saddles as well. Almost all the MIM Strats, with the exception of the Jimmie Vaughan I think. The rest of the Teles for MIM are a mixture. Some 6-32 and some M3, mostly.
