If you're in the business of repairing PCs, smartphones, or tablets, then you need the tools to help you get the job done in a fast, efficient, and safe way. Updated with reader suggestions July 2017.
Got a fastener that just always seems to work its way loose? Probably means the fastener is damaged, the thread is damaged, or you lost a washer that was helping to keep it down. Rather than overtighten the fastener (which will just make things worse in the long term), apply a dab of Loctite Threadlocker Blue compound. The blue stuff is designed to be undone with hand tools, so it won't cement the fastener into place.
Follow the instructions, and don't go mad with it!
