What to Do When a Hex Socket Screw Won't Budge?
3 Answers
The solution for a stuck hex socket screw is: You can use a hacksaw to cut a straight slot on the hex socket screw, then use a flathead screwdriver to remove it. For hex socket screws with longer heads, it's easier to handle—simply use locking pliers to grip the screw and twist it off. If the hex socket screw still won't come off, here are other methods: 1. Press a hard object against the screw and strike it forcefully with a hammer several times. 2. Soak the screw with kerosene or bolt loosening fluid before attempting to turn it. 3. Use an impact screwdriver. 4. If the screw is already stripped and not too small, you can weld it to a steel rod for removal. For smaller screws, drill out the entire screw with a drill bit.
Last time when I was fixing the garage shelf, I encountered a hex socket screw that just wouldn't budge - definitely rusted and seized up. I sprayed some WD-40 penetrating oil, didn't rush to turn it immediately, but let it soak for about ten minutes before attempting - patience is key here, otherwise you risk stripping the screw head. If you don't have professional oil, household cooking oil can work in a pinch, just drip some on and wait longer. The tool size must be precise, if the wrench is too small or too big it'll slip immediately, if all else fails try inserting a rubber band for extra friction. Don't force it, breaking the screw head would just create more trouble, better to let a repair shop handle it with proper tools. Prevention is more important - applying some anti-rust oil on screws regularly can save you lots of hassle.
A stuck screw is usually caused by rust or over-tightening. I often spray penetrating oil and wait for it to take effect. If the corrosion is severe, try gently heating the area around the screw with a small flame (never directly on the screw), as the heat causes the metal to expand, making it easier to turn. Impact drivers or impact wrenches work even better, but if you don't have the tools, placing a rubber pad between the wrench and the screw hole can help prevent slipping. Forcing it carries risks—you might damage the screw hole or even slip and hurt your hand. Reflecting afterward, regular cleaning and applying lubricant can prevent rust. If all methods fail, it's safer to visit a professional shop to have the screw drilled out.
