For this reason, Norbar Torque Tools Ltd and Insulated Tools Ltd have combined their respective skills and come up with what we believe is the best insulated torque wrench on the market.
Unlike all other insulated torque wrenches that utilise PVC dipped components, Norbar's wrench uses the much harder wearing injection moulded Nylon 11 on both the ratchet and adjusting knob.
The resulting wrench conforms to standard IEC 60900:2004 meaning that it has to pass an electrical test of 10,000 Volts.
The insulating material must also be able to function at temperatures from -20ºC to 70ºC, be able to withstand impact, be flame retardant, have good adhesion to the tool and have minimum moisture retention.
Our Insulated tool also carries the mark "Category C" which means that it exceeds the standard in terms of its impact resistance and has been impact tested at -40ºC.
