1. Use a Torx screwdriver
If the hex head of the bolt is only slightly worn, you can try using a Torx screwdriver. Choose a Torx screwdriver that is slightly larger than the original bolt, tap it gently to embed it into the bolt head, and then turn it counterclockwise to loosen the bolt.
2. Use a bolt extractor
For severely stripped bolts, a bolt extractor is your best choice. These tools are designed to bite into the damaged bolt and rotate counterclockwise to remove it.
3. Use an OGV screwdriver
OGV screwdrivers are designed for slightly stripped hex head bolts, and their sharp edges can bite into the stripped hex head. Choose the appropriate OGV screwdriver, tap it gently to embed it into the bolt head, and then turn it counterclockwise.
4. Drilling and milling
If the bolt head is completely damaged, you can use a drill and milling cutter to cut it off. First, drill into the hex groove of the bolt head to provide a guide, and then use the milling cutter to separate the bolt head from the threaded rod.
5. Heating and Cooling
Heating the bolt with a heat gun or blowtorch and then letting it cool naturally, repeating this process several times, can help loosen the bolt.
6. Using Penetrating Oil
Drop a few drops of penetrating oil on the bolt and let it penetrate into the threads. Wait for a while for the oil to soften the rust and dirt on the threads.
7. Physical Tap
Lightly tap the bolt head with a hammer and chisel to help break up the adhesion of rust and dirt.
8. Using an Impact Wrench
If the bolt is still difficult to loosen, you can try using an impact wrench. Tap the bolt lightly several times and then try to turn it counterclockwise.
Precautions
Safety first: Always wear appropriate protective gear such as non-slip gloves and goggles during operation.
Avoid Damage: When trying to remove a stripped bolt, try to avoid damage to surrounding parts.
