This Sirius Long Hexagon Allen Key is sized at 6mm, one of the most widely used metric hex sizes across the trades. It is regularly specified for automotive work, furniture assembly, machinery maintenance, and general engineering tasks involving socket head screws and bolts. Forged from alloy steel, it offers excellent resistance to wear and deformation, even under sustained use. The long arm design gives superior reach and leverage, making it easier to work in confined spaces and reducing the effort needed on tight or corroded fasteners.
