The bolts are rusting that connect my aluminum railings to my front cement steps. How can I fix this?

Welcome to the forums.
More than likely there are lead shields drilled into the masonry below those brackets.
Those bolts you are looking at are probably just plain steel lag bolts.
You could replace them with stainless or galvanized lag bolts. Take one out as a sample.
My guess is 3/8" x 3-1/2"

That's what I would call a hi low thread. Usually found on masonry fasteners like TapCons.
A hole is drilled into the masonry and that bolt cuts its own threads.
TapCon fasteners are great but in my opinion not the best type of fastener for a railing into masonry. I would definitely use a lead type expansion shield and a stainless steel lag bolt.
If what you are currently using is holding than I'm sure you could just repaint the bolt heads. It would probably be best to fully clean the head, reinstall the bolt and then paint it so the paint doesn't chip off from the wrench. Rustoleum paint should work well for that application.

I believe they are called LDT, by Redhead, or Large Diameter Tapcons. I still think lead anchors and stainless bolts will cure the problem, however.

Yes....might need to rough them up a bit and clean with a solvent (which won't hurt the stainless ability but would impact a galv bolt) and use oil based primer and paint. If your rails are black...Rustoleum make a very good hammered finish paint that says it doesn't need primer. They have it in other colors but it isn't normally carried at stores.

Paint doesn't adhere well to shiny/slick stainless so roughing it up is a must! Personally, I'd either clean up and paint what you have or switch to stainless and never worry about painting it.
