Track pad bolts for Lindeman

I scored a bunch of pads and need to know the right bolts/nuts to use. Do they make them specific for the application or will any carriage bolt work? Do they need to be heat treated and what is the length?

They do, but unfortunately, they are now $12/each, and no I am not kidding, I am working on a set for a customer now, and found this out.
Only other option I know of is to use regular carriage bolts and machine the square shorter in a turning lathe.

Lavoy what are the specs on the bolts? Dia. length and head dia? how thick are the pads? have a place in Ca. that can get almost anything when it comes to bolts

Basically a standard 5/8" carriage bolt, but the square part is about half as tall.

Thanks for sharing all your knowledge about crawlers on this site! I'm a newbie for sure on crawlers.
My Lindeman (with blade), was sitting outside for about 7 years under a blue tarp before I bought it. All the fluids were about half water. Engine was stuck but came loose fairly easily. The back plate has one corner broke off down low and the top threaded holes are stripped. There is about 1/8 inch gap where the mating steering clutch casting mates up to the back plate , both sides. The track pads are in bad shape. Both sprockets are welded on, one of which has been welded itself. Got my work cut out for me.

Update, the local dealer has the track pad bolts for $15 ea. He told me they were 1.4 in long.
Local hardware has the 1.5 inch long carriage bolts for $0.90 plus nut & lock washer. I bought a couple to see if I could make them work. The actual bolts I removed from the track were 1.6 in long. I did grind down some of the square shoulder on the carriage bolts I bought. They are probably the lowest quality steel found in the 3rd world countries. But I will see how these 2 work and handle the loads.
amazing thing - the first two pad bolts I tried to loosen came right off with a 1 1/16 open end wrench. I have not been successful in getting any others off. I have tried liquid wrench and heat with open end wrench, vise grips, channel locks etc. - no luck. Will try more heat next - red hot. I'm trying to save them for reuse is possible, although the replacement bolts, nut & washer I bought were only $1.30 each.

Most likely the bolts you got locally are grade two. Be careful, I have had more than a few head failures with the grade 2 carriage bolts, they pop right off under high tension.
