How to remove/install Couch Sofa leg screw/bolt

In most cases pliers will slip on the threaded portion of a bolt making removal difficult. Instead, use one of these methods.

Bolt removal

Use 2-5/16" nuts. It is helpful if one nut is larger than the other. Place both nuts on the bolt about halfway down. Then, jam tighten both nuts against each other. This is done by using two wrench's, turning each wrench in an opposite direction. When tight, place one wrench on the nut closest to the wood leg and turn the wrench counter clockwise to remove.
If you have a machinest vise handy, place the threaded portion into the vise jaws and tighten securly. Grasp the wood leg and turn counter clockwise to remove the bolt.

Screw installation

Hand turn and finger tighten the dowel screw into the leg. Then, start the leg containing the dowel screw into a pre-drilled (3/16") hole in the couch frame where the new leg will be. Begin to hand tighten the leg clockwise. As you turn the leg, the screw will enter the couch frame and will take turns tightening into the leg and then into the couch frame as you turn tighten. Turn the leg until it is flush up against the frame.
