Carabiner Triple Square Set saved my life. I partially removed a triple square head suspension bolt on an Audi S5 using an inexpensive tool. I was screwed. I was able to use this strong, hardened piece of carabiner to hammer it into a stripped bolt with a sledgehammer. Not what it's made for, though. This changed the screw pattern and allowed me to remove and replace the screw, saving me a lot of heartache. Well done and easily survived my crazy bullying. Excellent work.
