Hex Key Metric "T" B/E 4mm Bondhus BD13160
T-Handles: The T-Handle is the big brother of all handles. With a two-handed grip, operators can easily generate all the torque they need to insert or remove large or small screws alike. T-Handle Considerations: The T-Handle is the best selection for applications where maximum torque is needed for insertion/extraction of screws. Compared to a screwdriver handle, less effort is needed to generate comparable torque. The T-Handle is capable of producing a flywheel affect for 'spinning' fasteners in or out of low friction materials. A common misconception is that a shorter blade can generate more torque than a longer blade. In reality, blade length has no affect on torque.
