I’m guessing most of you know this one, but I didn’t when I first started working on boats, so it may be useful.
When cutting a bolt off that’s too long, first put a nut on it as shown in the above. Winding the nut off cleans up burs on the threads from cutting.
But even better, to avoid fragments that will make it difficult to get the nut on, particularly in confined spaces, before winding the nut off, grip it in the vice and use a fine file to clean up the cut end—only takes a moment and makes a world of difference.
