Hex Key Metric STD B/E 7mm Bondhus BD15770

The hex key is the best known hex tool in use. It provides an inexpensive and convenient solution for occasional or low volume fastener insertion or removal. Hex Key Considerations: Hex keys allow insertion and removal by spinning the blade between the fingers. Ballend hex keys are far more efficient than a straight hex blade, since they allow quick insertion from a range of angles. Even when working in wide open spaces, a ballend is a real timesaver. Easily carried in a pocket. Allows working in tight to reach areas. Hex keys require an extension handle to reach the full torque capacity of the long arm of the blade
