It's good to have something in reserve. But even better if you don't need it. All ISI  tools conform to DIN standards and are constantly checked for quality. The same is true of ISI accessories. They are designed to exceed the maximum ratings laid down in the DIN standards. A reliable piece of safety.  Universal joints, ratchet wrench, lever wrenches, sliding bars and extensions offer the ideal tool for every job. Even in special cases such as working in confined spaces ISI has the right solution for you, e.g. A ratchet wrench with a very small pivoting angle. All tools are available in ¼" to 1" drive head sizes.
