Why This Tool Is Worth It
Loose hex keys have a way of disappearing. A folding set keeps every size together in one place.
Each blade opens independently to 270 degrees, which helps when you’re working at odd angles on machine adjustments or hardware.
The square cut ends give a full depth fit in the socket, which helps prevent slipping and stripping fasteners.
