Should be an M12 X 1.5. Just make sure you get the correct length. If you go magnetic make sure there is internal clearance. If you have not gone from a crush washer to an o-ring, you should.

Seals just as well and you do not have to tighten it as much to seal.
KTM RFS bikes use the same socket (allen) head on the bottom of the motor. I swapped to hex head and use o-rings where crush washers were originally used. Have never had any issues.
