Don't buy the solid aluminum ones unless your never going to run a filter with aluminum threads in it. I put a cat filter on one and it galled. A filter wrench won't turn it. I'm going to have to cut it off

I'm a little confused-did the filter have steel threads & the filter base aluminum ones? Or were they both aluminum? I can't remember seeing a filter with aluminum threads before, and what were you filtering? Coolant, or fuel/oil/ATF?
They both have aluminum threads. It was a generic base, but any all aluminum base is prone to this. If the threaded boss is a steel insert it's ok. The filter was a cat 0750.
I ordered a new base with the threads in steel as I want to run the Catapiller 2 micron filters.
I've never seen a filter purchase that had an aluminum adaptor, nor I have ever seen an oil filter that uses an aluminum mounting base. Is that common on trucks and farm equipment?
Were both threads compatible? I have never seen this happen on something like this. All I can think of is that the thread size/pitch were not a 100% match.
I have been changing filters on my aluminum block trailblazer for years and it looks like the base is aluminum and the filter head is steel. I mean it has always been lubed with engine oil.
