i have never seen a filter that has threads to a certain depth. all spin on style oil filters have threads that are stamped into the hat and then goes into the filter cavity, with no limits on them for thread depth.
give an example of this you are talking about, and i will pull that PN off the shelf and take measurements, but i have never seen it happen, and i aint even gonna count how many oil changes i have done in the last 10 years.
and soak it with purple power, crank the pressure washer up to about 2500psi or more with a 10 degree fan tip, it will come off.
