There are many ways to solve the problem of screws slipping and not being able to tighten. Here are some common solutions:
Use fillers:
Toothpicks or matches: Insert a few toothpicks or matches into the screw hole with slipped threads, and then re-screw the screw. This can increase friction and allow the screw to be re-tightened.
Wood shavings and white glue: Fill some wood shavings with white glue into the screw hole with slipped threads, wait for it to dry, and then re-screw it. This method can not only increase the fixing effect of the screw, but also extend the service life of the furniture.
Solder: If you have solder at home, you can fill in the slipped area and then easily screw the screw.
Replace the screw or use a repair kit:
Replace a larger screw: If the screw hole is too large and cannot be repaired with fillers, you can try replacing a larger screw. This method is suitable for slipped threads in most scenarios.
Thread repair kits: Thread repair kits are available at hardware stores to help repair stripped threads. They usually include multiple thread inserts of different sizes to accommodate different screw sizes.
Use professional tools and techniques:
Screw extractors: Screw extractors have a left-hand design that can bite into the screw and pull it out of the material when reverse drilling.
Electric drill: Use the reverse function of the electric drill to easily remove the stripped screw.
Tap and vibrate to heat: Use a hammer to gently tap the periphery of the screw to create a small gap; or use a hair dryer to heat the metal screw to use the principle of thermal expansion and contraction to help tighten the screw.
Use lubricants or glue:
Thread glue: Applying thread glue can effectively prevent the recurrence of stripping and is suitable for screws that need to be fixed for a long time.
502 glue: Drop a small amount of 502 glue into the screw hole, then tighten the screw. The screw will not strip after the glue solidifies.
These methods can be used according to the specific situation. Be careful when operating to avoid further damage to the screw holes or related parts.
