If the screwdriver is constantly slipping on the screw head, you need to increase the friction force or torque. You can increase the grip between the screwdriver and the screw by using everyday items. For really stuck screws, you need specialized tools, but most are quite inexpensive and very common.
Steps
Using screwdrivers
- If screws are caught in metal, spray anti-rust oil like WD40 and wait for about 15 minutes. [1] X Research Source
- Use the largest screwdriver that will fit the screw.
- If possible, use a wrench to clamp the screwdriver handle to increase torque.
- Wide rubber band
- Steel wool pad
- Blue abrasive dishwashing sponge
- Cloth tape, with the adhesive side glued to the screw head
- This is a good choice if the screw to open has a bake head.
- You can also use a square hole drill to drive into the screw head. Close until the drill bit penetrates the screw head.
- If the screwdriver slips, you must stop turning it immediately. Letting the screwdriver slide continuously will only cause the screw head to wear more and be more difficult to open. Make sure you are turning the screw in the correct direction, usually counter-clockwise (but not always). Pressing down firmly while turning the screwdriver will help prevent slipping.
- This method is very effective if the screw is already attached with adhesive.
Using a screwdriver
- Electric screwdrivers should not be used as excessive force may damage the surrounding material.
- The screwdriver head used to attach to the screwdriver usually has a very high hardness to meet the job requirements. [5] X Research Sources
Use a snail extractor
- For Torx screws or keyhole screws with a protruding cylinder body, a multi-tooth extractor is recommended. This tool fits over the screw head, and is held in place by the teeth on the inside. Instead of following the instructions below, you’ll tap this screw extractor, then rotate it to remove the screw.
- Wear eye protection to avoid splashes of metal. Always wear eye protection while working.
- Some extractor kits are sold with a nut that fits onto the tip of the tool. Use two wrenches to tighten the nut to an angle of 180º to make the torque more balanced.
- Be careful not to damage the surrounding material. Whether you’re working with metal, it’s best to use a heat gun or torch when propane is used. Continuously move the burner around the snail to avoid burning in any position for more than a second. [11] X Research Source
Other methods
- If you can’t find the right size nut, you can stick a smaller nut on top of the nut. But a small nut will not produce as much torque as a properly sized nut.
- If the screw head is not flat, file or grind it with a grinder to create a flat surface. Then, punch a hole in the center and drill through it.
Advice
- If you can reach the back of the fastener, see if the body of the screw goes through it. If the screw body pierces the object, use the screw clamp and screw it out from the back.
- Make sure you are turning the screws in the correct direction. The screw may have a reverse thread, in which case you must turn it clockwise to open it.
- The one-way screw can also be opened if needed. Search online for a one-way screw opener.
- If the hole is chipped after removing the screw, there are several ways you can fix it:
- Punch a larger hole. To increase stiffness after punching, apply a loctite threadlocker to the hole and install the helicoil stud.
- Screw a larger self-locking screw into the chipped hole.
- Use bolts and nuts. If you need to connect two metal objects, weld the nut to the metal to create a threaded connection.
Warning
- A chipped screw metal edge can cut your hand or cause the device to malfunction. You should use a file to round this metal edge.
