I am looking for something like a t-bolt but sized for the miter slots on a table saw. The base needs to be 7/8” wide. The widest t-bolt I have found on woodcraft or rockler websites is 9/16” wide. I need to be able to connect various knobs for hold downs and jigs. Thanks for your help.

Here is a source that seems to have them.

Personally, I usually use these for my jigs.

Toilet bolts are available in both 1/4” and 5/16” and in they should turn and wedge just about right in the slot. For my saw, I have to use the items like Charlie refers to because my old saw does not have a t-type slot. Those items simply expand and clamp to the sides of the slot so they will work with any type of 3/4” W X 3/8” D slot. I have even made similar ones from wood. It works pretty well, but you have to use a good hard wood like rosewood or something. Anything soft just crushes the wood and the next time you use it, it won’t grip in the slot.

Are the slots in the table wide enough to accept a toilet flange bolt?
I use them a lot for jigs but, my table doesn’t have the slots in the edges of the miter gauge slot so, I don’t know if they’d fit.

I’m curious what kind of applications would call for a t-bolt in a table slaw miter slot.

If you can’t find a bolt for the “tee”...

- Drill and countersink a hole for a 1/4” bolt in the bottom of a strip of wood that fits your slot.
- Cut a thin slot from one end of the strip to the hole
- From the bottom, insert a 1/4” flat head bolt
- Mount your jig to the top and install your choice of washer and nut

The wood strip will expand as the nut is tightened and the bolt head is pulled into the countersunk hole. It can generate a surprising amount of holding power.

Here's a commercial version of the same method.
