This tool is specifically designed to aid in installing threaded inserts.  It has features which interface with the slots on the threaded inserts to screw them into place.  It is much easier to use than a slotted screwdriver because it won't slide out of place, and won't interfere with the topsheet as the insert bottoms out.  Designed for use with any 1/4" hex screwdriver.  Due to feed back and demand we have increased the tab sizes to better fit the inserts and also upgraded the quality of steel to make the tool stronger.  Thanks to everyone that emailed us and helped us improve the tool!
