Review on TEKTON 4971 2 Inch Extension 3 Piece by Donnie Boss

These quality extensions seem to last a lifetime. I have used them with my TEKTON 15356 1/2" drive from 24" breaker bar and they work great. They are very tight on keys and sockets. In fact, they are quite difficult to remove, so they fit nicely. Although I don't see that as a disadvantage. You need a tight fit for something designed for use in an impact wrench. This set comes with 3", 6" and 8" extensions. The diameter of the shaft extension is approximately 1/2". Pros: * Very tight fit * Can be subjected to a lot of torque Cons: * Not yet Additional Considerations: Note Note that they are designed for 1/2" and 1/2" at the end of extension. Overall: 5/5 stars (>=0.5 round up, <0.5 round down) => 5 stars
