Allen keys are l-shaped spanners which have a hexagonal cross-section that is designed to fit into and turn small bolts and screws. This is done via a hexagonal socket contained in the head of such consumables.
Our range includes metric and imperial-sized hex keys, with either standard ends or ball ends which allow the tool to be used at an angle off-axis to the screw. These devices can be purchased both individually and in sets.
