Scott, I think what you are after is a "T" nut. If you are looking to have the piece that goes into the camera bed and the tripod screws into it this is what it is called. Be sure to get the one that you can use small screws to attach it to the bed. Do not get the one with the barbs that you have to pound in. Depending on the camera size and your tripod head you have a choice of 1/4-20 or 3/8-16. I used the 1/4-20 on my 8x10 and 8x20 and on my 11x14 I used the 3/8-16 to help support the heavier camera. I use mine without the quick release plates.
