HNSC Hybrid Blocking Wrench No. 15

Hybrid locking socket wrench, curved. This hybrid tool is made of CrV steel. The head has a twelve-helical design. These wrenches are used for work with voltages up to 1000 V AC or 1500 V DC. Designed for locking screws and nuts when loosening and tightening screw connections on distribution equipment, particularly when replacing fuse bases.

We use a laser to mark these tools, ensuring they are legible, high-contrast, and durable. This is a new feature among our tools. The size is also traditionally embossed on the head.
