Wing Bolt Wrench - Set Rental

Beechcraft has been changing the hardware for the wing attach bolts and nuts. It used to be that all of the bolts had an internal wrenching hexagon socket head. This would require a tool like an "Allen Wrench" to hold for torquing. The new ones come with a twelve-point external wrenching head. These require a tool that looks like a twelve-point socket to engage. The older aircraft had an internal wrenching nut on the wing bolts. Approximately 1991 they switched to a nut that is external wrenching and has twelve points. It is possible that some of the new hardware has been installed on the older air-frames. For this reason, it is difficult to forecast which tools may be needed on a given plane without examining the hardware installed and any replacement nuts and bolts to be installed. Recently our set of wrenches was expanded from a total of 10 to 12. The two new wrenches are four-inch torque extenders that have a twelve-point socket on one end. The new sizes are 3/4 and 13/16ths.
