Sirius Long Hexagon Allen Key Metric

This Sirius Long Hexagon Allen Key is sized at 3mm, a popular metric size well suited to smaller fasteners found in machinery, bicycles, electronics casings, and general mechanical assemblies. Its compact size belies its professional build quality. Forged from alloy steel, this key resists wear and maintains its shape under consistent torque application. The long arm design improves access to recessed fixings and provides greater leverage than short-arm alternatives.
