Tow Recovery Eye with Internal Threads

Currently vehicles are towed or recovered using a screw in eye that attaches through an opening in the front or rear fascia into the body structure/frame or bumper. The vehicle's body structure/frame or bumper threaded insert (barrel nut) may become corroded or contain debris causing the owner or tow operator to only be able to engage a few threads until there is resistance, falsely indicating a fully seated tow recovery eye, which creates a safety issue.

Method

     Tow recovery screw in eyes have external threads that screw into a threaded insert. When the vehicle becomes disabled and requires a tow, the tow recovery eye is removed from the inside of vehicle and inserted into the threaded insert. If the tow recovery eye does not fully seat, then the loads applied to the eye do not transfer within the entire system and therefore could cause the tow eye to break.

New Approach

An externally threaded post, attached to the vehicle's body structure/frame or bumper, allows for debris to fall off of the post instead of being trapped like a threaded insert. The owner or tow operator will be able to engage all of the threads until the tow eye is fully seated.
