What are they using for the screw size in a metal door ?

If you have new screws, satisfy your curiosity by taking them to the
Box Store and seeing which size nuts will fit. Odds are your 6 mm was
the one at fault and I'd bet the new ones you have are 6 mm. Remember
the Chinese are prone to use machine cutting tools until they break,
but not until they are worn off size.
