Jam the flat tip into the newly made screw slot, and push and turn at the same time. Make sure the slot is wide enough to accept the largest flat blade screwdriver you own while still providing a tight fit. Still wearing your heavy leather gloves, cut a new straight slot deep into the screw head using a rotary tool and a cutting wheel. If your rusted screws remain stuck or you’ve stripped the screw heads, try cutting a notch into each head and removing them with a flat blade screwdriver. Philips and star head screws can’t handle a lot of torque without stripping. METHOD 2: Cut a New Groove into Stripped Screws If the rusted screws still won’t budge, move on to the more aggressive methods below. Locate the bit in the screw, hold the tool with one hand and strike the impact tool with your hammer. Set the tool to rotate counter-clockwise and choose an impact bit that fits snuggly into the screw head. A hand impact driver converts straight hammer blows into a twisting motion force while forcing the bit deeper into the screw head at the same time. That means it reduces the chances of stripping the screw head while increasing your chances of a successful removal. Before you start, don eye protection and wear heavy gloves to protect your hands in case you miss the head of the tool. If that increased torque doesn’t help, switch to a hand impact driver and a ball peen hammer. Lean into the screwdriver to keep the tip engaged with the screw and turn the screwdriver with the wrench. If your screwdriver is equipped with a hex-shaped bolster near the handle, you can more leverage and twisting force by sliding a box-end wrench over the bolster. Just stir a few drops of water into a half teaspoon of cleanser, press the paste into the screw head, then jam your screwdriver into the screw head and twist and push at the same time. You can make your own gripping paste, though, using an ordinary powdered kitchen or bathroom cleanser. This is the point where pros add a dab of automotive valve grinding compound to the screw head to act as a “gripping paste” to get more grip between the screwdriver tip and the screw head. If your screwdriver slips out of or starts stripping the screw head, stop! Adding more force will just strip the screw head, making it even more difficult to remove and impossible to re-use. When you return to the task at hand, smack the screw head several more times and then tap the metal surface around the screw head to drive the penetrant deeper into the screw threads. Next, take a 15-minute break to let the rust penetrant work. If you don’t have those supplies, you can use a general purpose lubricant like WD-40 it just won’t work as well or as fast as a rust penetrant fluid.Īfter striking the screw head several times, apply a liberal amount of rust penetrant around the screw head. Don’t have any rust penetrant? You can make your own from a 50/50 solution of acetone or nail polish remover and transmission fluid or sewing machine oil. STEP 2įind rust penetrant at any hardware or home center store for around $6/can (Liquid Wrench, PB Blaster, and WD-40 Specialist Rust Release are three popular brands). The hammer blows crack the rust, creating channels for the rust penetrant to seep in dissolve and lubricate. – Closedend wrench to fit screwdriver bolsterįirst, break the rust’s bond by applying several swift hammer blows directly to the head of the screw. – Acetone or nail polish remover (optional) If the gentle methods don’t work, then move on to the more heavy-duty methods (#2 and #3) to remove the rusted screws. Always start with the most gentle means of “persuasion” first to avoid damaging or breaking off the screw heads.
