Wiha Tools Insulated Torque Screwdriver Set, Tip Size 4 mm, 5.5 mm, 6.5 mm, Torque, 2 in-lb, 18 to 62 in-lb

These insulated adjustable torque bit screwdriver sets come with insulated handles and shafts to protect against electrical shock from live electrical circuits and are suitable for use near electrical components when tightening and loosening screws. The insulated handle also allows for a more secure grip when turning compared to a noninsulated handle. Insulated adjustable torque screwdriver sets have extra handles that are proportioned to optimize torque range and tool bits so they can torque a variety of screwhead types and sizes. The handle is turned to rotate the screw and the tool makes a "click" sound when the desired torque has been reached.
