Loosening a stuck fastener is no fun. You can strain, struggle and still not get it done. Today you'll learn how to free up tough stuff, whether a stripped or frozen screw, bolt or nut. Step one is to be sure you're turning it the right way -- right is tight and left is loose. Indeed, "righty tighty -- lefty loosey." When removing nuts and bolts in metal, too much force can round off corners. Use science instead; add heat and penetrating oil then tap with a hammer, wait a few minutes and try again. For damaged round head screws with worn slots, cut a new slot across the old one with a hacksaw. If that doesn't work, file both sides flat, and turn with pliers or an adjustable wrench. For hard-to-turn screws, add torque with a wrench or pliers on the screwdriver shank. And, for any fastener -- should the head break off -- there are extractors with left-hand thread action that, when turned counterclockwise, burrow into the stuck fastener and start backing it out. But before you start serious sawing and drilling, you may find simple science makes difficult fasteners more willing. Try it! And that's the On The House Tip for today.
