This Sirius Long Hexagon Allen Key is sized at 17mm, one of the larger metric sizes in this range, making it well suited to heavy-duty industrial fasteners, structural fixings, and large mechanical assemblies where substantial torque is required. Constructed from alloy steel, this key is engineered to handle the higher forces associated with larger hex fasteners without risk of deformation. The long arm provides significant mechanical advantage, enabling greater torque application with less physical effort. Features and Benefits: • Alloy steel build designed to handle high-torque applications • Long arm provides substantial mechanical advantage for large fasteners • 17mm metric size suited to heavy engineering and industrial tasks • Robust construction for repeated use in demanding environments • Professional standard for trade and industrial use Specifications: Size: 17mm Arm Length: Long Hexagon Type: Metric
