I use stainless fasteners almost ever day and also break loose by hand then use power tools to remove and reinstall, I only use known good fasteners and will verify the thread quality with a high quality tap and die set when we change suppliers.when possible source all of your fasteners from a single source reputable manufacturer, as they will use a thread standard across their product line. If I am noting -any- drag or resistance on screws I will run each one of them through a die to clean up the major diameter and thread pitch. Two things I always have on my bench are a stick of door-ease type stick lube ( regular bees wax works well also ), and loctite 242 ( blue ) which actually helps lube the threads when installing screws.
