Hello, thank you for the question. This item does not come with an M12 thread so would not be suitable for M12 accessories. As the product is manufactured to a specific specification i cannot recommend modifying the item in anyway as it could weaken the design reducing the thread size. In theory the factory thread is wider than M12, so it could be reduced to M12. However it would not be feasible to do so with a hand held die as there is too much material to remove this way, and also the metal is very hard. Regards, Hilka Tools
