Will this fit my 2021 ultra limited flhtk?

Yes, this is the highest performing battery for that bike. Thank you,

Is this battery fit 2019 Shelby GT350?

I dont know for sure, but probably smaller than factory battery.

what size bolt and thread pitch are the terminals on the battery

All models are the M6 size with a 1mm pitch with the exception of the AG-401 and AG-801 which have an M5 with a 1mm pitch.

Will this fit my 2015 rode glide

Yes it should fit your Harley and weighs about 20 pounds less. Dont forget you need a special battery charger if trickle charging! I have had mine for about a year now starting a 393CI engine in my car and I love it. My only concern is how long it will last for the price.
