But first, here are some of the best tools for the delicate and not-so-delicate work of removing stripped screws. We explain all this in greater detail below. You drill into the damaged fastener and go from there. If the head of the screw is set deep, if the fastener’s head has snapped off, or if the head is so severely rounded that not even locking pliers can grip it, you’ll have to employ an internal removal process. Either grip the screw or bolt head with a pair of locking pliers or use a socket specifically designed for extraction. If it is, and you can get a grip on it, then you opt for an external removal method. In the simplest terms, there are two ways to deal with a stripped screw, and it all depends on whether its head is above the surface of the material into which it’s driven. You can get so good at it, you almost look forward to the challenge. Getting the upper hand in these situations is satisfying. Reach for the proper extracting tools and set about the methodical work of removing the stripped screw or bolt. You might be laughing when you read this, but surely you weren’t the last time this happened to you. And then you’re left wondering how to remove that stripped screw or bolt.

You may behead a bolt so violently in trying to remove the thing, you may go flying too. Or for that matter, it can seem like before you can even get up some momentum, disaster strikes when the first screw or bolt strips. The closer you get to completing a project, the more likely you will be to run into one. Few things will try your patience the way a stripped screw or bolt can.
