[This review was collected as part of a promotion.] When I found these locking hex keys, I grabbed them. The push button release allows easy access to the key you need. The keys don’t flop around and get in the way when you are trying to use one. When closed, this device takes up little space in my bag and stays out of the way until I need it. Sizes range from 3/32”-1/4”.

I bought this several months ago to fit the few metric hex heads I come across. I bought both the standard and metric at the same time. These are very handy to keep in your tool pouch with all of the keys quickly available. It keeps me from having to search for random hex head winches and helps me keep myself organized.
