If you have a bolt that you need to tighten-up, screw-in, or work on, but it’s old, nasty, rusty, and won’t allow you to screw a nut onto it, chances are you’ll have to go find a new bolt with the exact same size and length. Though, you wouldn’t have to if you had the Uniburr! It’s a unique drill attachment that lets you easily fix the ends of broken or rusted bolts to easily reattach a nut.
