hi, i want to make a wedgie sled for cutting segments and am using T track for the adjustment, however I bought one track that is made for .25” hex bolts. can you use .25” hex bolts or .25” carriage bolts with track made for t track bolts

Never tried carriage bolts with that t-track before. The track McMaster-Carr sells has a slot opening that is .343” wide so the square part of the carriage bolt would need to match or it wouldn’t work. Also, the head on the carriage bolt would need to be less than 7/16” wide.

My preference is to use 5/16”-18 elevator bolts and cut the flanges to fit. A cut-off wheel on an angle grinder does this quickly but it’s still time consuming to trim and deburr if a lot of bolts are needed. Still, I think it’s worth the effort because the result is a bolt that slides smoothly and doesn’t create burrs on the t-track. 1/4-20 bolt heads tend to hang up on occasion.

Looks like you’d need to grind the heads on carriage bolts to use them. The square part on a 5/16”-18 bolt is about right but the head is .719” wide.

Toilet flange bolts are also good. Some HW stores sell them separately.

+1. You will probably just have to cut them to length.

- Karda

it depends on the track. I ran into some a long time ago that a toilet bolt fit fine but a 1/4 20 hex wouldn’t quite get in, but most will either do a toilet bolt, or a 1/4- 20 hexhead, unless they are the 3/8-16 variety.

Yes, you can just grind the sides off of the carriage bolts. I do it all of the time.

T tracks can be aggravating. It seems there are different sizes, for example some take 1/4” hex head bolts, but will not take a regular T track bolt.

IME the toilet bolts will usually fit.

FWIW, the Incra tracks are larger and will take a Festool track saw clamp.

I know you just ordered the T-Track. For future reference, this is the type I use, the Rockler Universal T-tracks. It accepts 1/4” & 5/16” T-bolts, and 1/4” hex head bolts. I keep extra on hand in case I need to make a quick jig. https://www.rockler.com/shop?w=t-track
