Electrical-Insulating Adjustable Torque Wrenches
Insulated to protect against accidental contact with live electrical circuits, these wrenches are tested to 1,000 volts to meet IEC 60900. Set torque and the wrench indicates when it's reached with an audible click and an impulse in the grip. To relieve pressure on the spring and maintain calibration, set torque to the lowest reading on the scale when not in use.
Note: Accuracy ratings do not apply to the lower 20% of the torque range.
Calibration certificate traceable to NIST states the product has passed a test for accuracy.
Calibration certificate with test data traceable to UKAS includes the test measurements that confirm accuracy.

Electrical-Insulating Torque Screwdrivers
An insulated handle and shaft protect against shock from accidental contact with live electrical circuits. These tools are tested to 1,000 volts to meet IEC 60900 standards. To adjust torque, remove the insulated cover and turn the collar. Drivers signal with an audible click when the set torque is reached. They come with a calibration certificate that is traceable to NIST and includes the test measurements that confirm accuracy. Use with screwdriver bits (not included).
Note: Accuracy ratings do not apply to the lower 20% of the torque range.
