This 1/4" brass screw is going to be used on an MHS double threaded Jaded grips section, so I'll need to shorten it by about half. I'll use a rotary tool and a reinforced cutting wheel for the job.

I'll be using the 8-32 nut to secure the screw in the vise grips to prevent damaging the head of the screw, and to also help with maintaining the integrity of the threads:

I inserted the screw into the nut.....and then placed the nut/screw assembly into the vise grips:


I set the rotary tool to a high speed, then I used slow, steady pressure on the tool and carefully cut it off:





There we go! All shortened!

DO NOT TOUCH THE SCREW!!!! IT IS HOT!!!!

I'll use a pair of pliers to get the screw and nut out of the vise grips:




Now I'll use the Allen wrench to back the screw out of the nut:

This will also help to clean up the threads you just cut through.

And then install in into the double threaded Jaded extension:




Now the screws don't stick through into the inside diameter of the part, and you can easily fit an MHS speaker mount and battery pack in there with no problems:
