HNSC Hybrid Blocking Wrench No. 12, for up to 1 kV AC / 1.5 kV DC

Hybrid Bent Locking Socket Wrench. A hybrid tool made of CrV steel. The working head features a 12-point design. These wrenches are used for live work on equipment under alternating voltage up to 1000 V or direct voltage up to 1500 V. The wrench is designed for locking screws and nuts during the loosening and tightening of bolted connections in switchgear devices, especially when replacing fuse bases.

We use a fiber laser to mark these tools, ensuring high readability, contrast, and durability. This is a new solution among the tools we manufacture. The size is also traditionally embossed on the working head.
