Description
T-Nut for all brands of Backbox receiving bolts.(see Photo Gallery)
3/8″ with a 16 thread pitch.
4-prong for a even bite.
Many times you will find these are missing, or stripped.
Very difficult to replace correctly, unless you remove the entire playfield.
Once installed, each should have two 3/8″ to 1/2″ pan head screws screwed in beside them to keep them in place when bolts are tightened.
