1000V INSULATED TORQUE SCREWDRIVEROne of the main advantages of our 1000V Insulated Torque Screwdriver Set is the precision torque control. This feature is crucial when youre working on switch gear and consumer units helping alleviate the risk of damaging terminals, arcing circuits, or hot spotting. However more importantly it stops you under or over tightening terminal screws. Each individually calibrated torque screwdriver ensures precise, easy adjustment between 1. 0 5. 0 Nm.
