I just cut flutes in the bolts used for clean out a lot like a tap is set up using a carbide cutting wheel. The OEM hardware has the correct thread pitch grade for the threaded hole so it has no tendency to cut at the threads. Thread taps are sometimes a larger fit grade than they should be and they will cut the threads deeper. It's just to clean the crap out. The rest will blow out with compressed air. This insures the thread pitches will remain as tight as possible. It's important for studs to be relatively tight. Loctite might work but it depends on a lot of factors on how well it works.
