Sirius Long Hexagon Allen Key Metric

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.
