Best way to orient Electric Screwdriver to avoid cross-threading

Cross-threading is one of big problem during tightening, this is usually caused by the fastener being applied at an angle to the proper position and being forced onto the bolt. The threads of a bolt or nut are designed to interact with the axis of every aligned, which allows the peaks and valleys of the threads to slip across one another. During tightening, the Electric screwdriver needs to fixed perpendicular to the work surface. If bolt or nut is available at the top of the work surface, it can be managed by the operator but after practice, if bolt or nut position is different it will be very difficult for the operator to manage the perpendicular position of Electric screwdriver.

To avoid the cross-threading need to use Arm and fix the Electric screwdriver in these Arm. KILEWS provides torque Arm along with Electric screwdriver for accurate tightening and to avoid cross-threading.
