internal wrachet -open/closed wrenches w/ swivel head.
I didn't buy a set when they first came out because I was sceptical and too cheap. Figured I didn't need such fancy bourgiouse things. After much swearing -I just picked up a set out of need (auto-quad intake manifold nuts) and the 5 degree close wratchet mechanism is great. They seem pretty solid. It says on package "do not use to free bolts. So, I'll have to remember that -
A friend left one out on a job site in the rain for three days. He was able to free the wrachet by soaking in light oil. Good to know. He has abused his daily with good results.
I really like them and have been telling myself what a fool I was for not buying them sooner. Great time saver. Good for tight spots.
A great new addition to the tool department. Does any one else like these things? Has anyone stripped the internal wrachet mechanism?
