Proto Hex Key, Tip Size 3 mm, Long Arm Length 6", Short Arm Length 4", Black Oxide

T-shaped tether-ready hex keys have a collar that allows the attachment of a tether where the tether is attached to the user or a fixed object to prevent the tool from falling and causing injuries or damage when working at height. These T-shaped hex keys have one long arm with the drive tip at the end, and two short arms that form a T-handle that can provide more torque than an L-shaped key.
