The only way I've done this before was to take what I could of the old bits of the threaded socket and lightly superglue them in place. I then scored the area around it with an xacto knife. I made a rectangular form as large as would fit inside the empty space around the standoff before filling it with JB Weld. After fully curing, I filed and fitted the JB block to fit snug with the hinge.

I had to rebuild the bezel side also as the cylindrical area had cracked out. With that side, I completely filled it, then used a drill press to recreate the hole. It has been nice and solid since but admittedly, I've also been rather ginger with it too.
