    Electrically Insulating Ratchet Wrenches

    Image of Product. Front orientation. Ratchet Wrenches. Electrically Insulating Ratchet Wrenches.
    Insulated to protect against accidental contact with live electrical circuits, these wrenches are tested to 1,000 volts to meet IEC 60900. A ratchet mechanism allows you to turn fasteners without removing and repositioning the wrench. The smaller the turn required to ratchet, the less clearance you need to engage the ratchet.

    Electrically Insulating 12-Point Socket Sets

    These sets organize what you need when working around live electrical circuits. Attach one of the insulated sockets to the included wrench. All components are insulated to protect against shock and tested to 1,000 volts to meet IEC 60900 and ASTM F1505 standards.
    With twice as many corners, 12-point sockets grab onto hex-drive fasteners more quickly than 6-point sockets. Also known as double-hex sockets. For use with hand-drive tools only.

    Image of Attribute. Front orientation.

    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 they will indicate 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. These wrenches come with a calibration certificate, which includes test measurements that confirm accuracy.
    Torque—You can tighten fasteners that require less torque than the values listed, but the accuracy ratings apply only within the specified range.
