Bolt is the star of the biggest show in Hollywood. The only problem is, he thinks the whole thing is real. When the super dog is accidently shipped to New York City and separated from Penny, his beloved co-star and owner, Bolt springs into action to find his way home. Together with his hilarious new sidekick Rhino, Bolt’s #1 fan, and a street-smart cat named Mittens, Bolt sets off an amazing journey where he discovers he doesn’t need super powers to be a hero.
The extension is to limit torque, it is almost impossible to show this demo on a regular 19mm bolt with very powerful impact unless you can find a stuck crank bolt which can be tough if you are using 1000ft-lbs impact guns. If you would like to see the weight comparison of sockets they are in this video: https://www.youtube.com/watch?v=SGbYcLobC3M .
Here is my homemade 19mm heavy crank pulley bolt impact socket from this video https://www.youtube.com/watch?v=4c5uNnggwZU works great…but sometimes doesn’t work (as shown at end of video) but I read the same with the real crank pulley sockets like the Bluepoint CBSM19 or Lisle 77080 they don’t always work…so sometimes the bolt must be so tight you just need a bigger impact wrench or heat.
But I bet these heavy sockets would help 99 percent of the time unless you have a really weak impact then nothing will help. The lisle is probably made the best because it is one diameter all the way to the front. You could make a heavy socket for ANY size nut or bolt.
