FELO brand adjustable torque limiting screwdrivers allow users to set the desired torque level at the top of the handle. When the preset torque level is reached, the mechanism slips and makes an audible "click." Three models cover a torque range from 5.3 inch pounds to 47.8 inch pounds. The handle only limits torque when rotated clockwise. Full torque with no limits is achieved when the handle is rotated counterclockwise.
