Stanley 94-149 Long Hex Key 12mm

The Stanley 94-149 is a 12 mm long hex key (Allen key) in metric size, used for fastening and loosening hex socket screws and bolts. The long arm gives extra reach and leverage on large fasteners. Stanley states it is built for high durability and a long working life, and that the key also lets you guide a screw into its hole while protecting the contact surfaces of the screw or bolt from outside damage.
