Knipex 98 01 13 KN | Offset Box Wrench, 13 mm, 1000V Insulated

A Single Box Ended Wrench is a hand tool designed for turning nuts, bolts, and fasteners with a hexagonal (6-point) or bi-hexagonal (12-point) socket at one end. The enclosed, box-shaped design allows the wrench to grip the fastener securely on all sides, reducing the risk of rounding off the edges and providing greater torque compared to open-ended wrenches.
