Double "T" nut

[Frank S]

I use it quite a bit for clamping odd shaped parts with 2 hole down clamps. I could always just use 2 T nuts but this one is just handy and then there are the odd times when I need the clamp to be in the positioned outside of the slots that is when I too use a blunt nosed grub screw to secure the t nut in the slot and the clamp bolt in the other hole. Instead of over tightening things down I add more clamps. IT works especially well when having to edge clamp the nut can be secured then the lateral clamping force put much less strain on the table slots
