To fix damaged or stripped bolt threads, you can use a thread repair kit or a tap and die set to rethread the bolt. First, clean the damaged threads with a wire brush. Then, use the appropriate tool to carefully rethread the bolt. Be sure to use the correct size and pitch for the bolt to ensure a proper fit.
To fix threads on a bolt, you can use a thread tap to clean or re-cut the damaged threads. This tool helps to restore the proper shape and size of the threads on the bolt, allowing it to securely fasten with nuts or other components.
To fix stripped pedal threads on your bike, you can use a pedal tap to rethread the damaged area. Make sure to clean the threads before tapping and apply grease to prevent future stripping. If the damage is severe, consider using a helicoil insert for a more permanent fix.
To fix a stripped bolt head, you can try using a rubber band or a piece of steel wool to create more grip, or use a specialized tool like a bolt extractor or a tap and die set to remove the stripped bolt.
No way to fix that - your tank is scrap.
If the sensor is stripped you will have to replace it. If the fitting or hole it threads into is stripped it is likely you can make oversize threads and use a fitting called a bushing to repair it. Mind you I got desperate one night and epoxied one in. Its still working but if I ever have to change it I am toast.
Heli-Coil
You have a few options. I it is not stripped just replace the gasket. If the threads are stripped or cross threaded, you need to have it repaired at a welding shop. They can easily fix this problem. Purchase a new drain plug and seek out a good shop.
Ask the garage for a helicoil repair.
can use a threaded rod that matches old bolt threads, that it can reach the bottom where the threads aren't pulled out, if there is none then you need to use a HELI-COIL or thread repair incerts, most automotive supply house carry them, just need a drill an bit the size for incert to do the repair
To fix a cross-threaded nut, first, remove the nut carefully to avoid damaging the threads further. If the threads on the bolt are still intact, you can use a thread file or a die to clean them up. For the nut, you may need to use a tap to restore the internal threads. If the damage is severe, replacing the nut or bolt may be necessary.
You will probably have to re-thread unless you can get a SLIGHTLY over sized bolt to thread and seal
YES, You must either drill it out and retap it to the next bolt size up are drill it out and install a heliecoil in it.
