Seat track mounting bolts

[fy469rtse]

Any one know where to get the correct bolts for mounting seat frames to seat tracks
Flat head not raised, and with square ledge under head to fit square hole in frame, can't use normal bolts here as they will interfere with the seat tracks movement

I'm in the same boat with you fy469rtse.
Mine is driver side only. Previous owner had wooden riser blocks to raise the driver seat. They grinded off all 4 studs then used 2 1/2"carriage bolts (OEM studs are 1 3/4"). On the seat tracks there are 3 square cut out positions for each stud. They moved the carriage bolt to the most forward position. The factory studs that were shaved the heads are still in the tracks, probably too lazy to pop them out or didn't have the proper tools. Like you said using carriage bolts would interfere with seat track movement. Plus don't they use a stronger grade of steel for the factory studs vs a standard carriage bolt?

Going to go to a industrial bolt supplier, will let you know,
We call them coach bolts here, going to see if they make them in high strength,
What size do you think they are 1/2 or 7/16 , in you photo , coach bolt with the dome of the bolt machined flat,
If I can the square part to fit, I think it will work,
Will post how I went , Sunday here so tomorrow I will pick some up

Thread diameter is 5/16". Wrench size is 1/2". Stud length is 1-3/4". Stud length was measured from the underside of the track to the end of the stud and not from the top of the head.
Let me know what you find. I'm scouring the internet for a match.

I'm also looking for the bolts that bolt tracks to seat frames, similar bolt just a shorter version of these , again the heads are low so when the seats are are adjusted back and forth they don't again catch or interfere with the tracks movement

Ok found mine for seat tracks and new mounting studs through floor,
The trick is to know what terminology to use ,
There called carriage flat head bolts,
found them in grade 5 & grade 8's,
Ordered 5 1/6 studs to tracks to floors, also ordered the shorter ones to mount tracks to seats,
Order mine locally, readily available,
Hope this helps anyone else on here looking for the same thing

Is there a location to order these bolts, I looked at a couple of bolt locations and they only have rounded carriage bolts.

Elevator Bolts!  You can pick them up at Lowes and they work perfectly.  Even spot weld them in place if you like.
