Repair worn threads for floorboard screws.

[Jim/GA]

I did a helicoil on a couple and I was not impressed. There is nothing there to hold the coil in place. It wants to screw all the way through as you install the floorboard screw. I tried a drop of thread lock but it didn’t hold.

Tapping to a larger size screw works.

Or replace the d-nut before you paint.
