Well, I know in common parlance people use "stripping threads" and "cross-threading" interchangeably, but as a machine design engineer, stripping threads means that you overloaded too few (or soft/weak) threads and the threads were sheared off under axial load. Cross threading means the threads did not follow their intended path and as a result the peaks of the threads were flattened creating a crappy new thread path.

It was so annoying. I was having trouble getting the screw in smoothly. I pulled the pin and tried the screw in my hands and it as tough to get it to fit in, so I figured the resistance was natural. But the e-brake cable ads an annoying side load. I thought I had it, but obviously did not. I'm hoping new screws will fix this. Unlike other cars, where screws are very cheap, these are meant to be reused. They are $8 a pop. For Mazda screws.
