Rated 3.4 out of 5 by 14 reviewers.
Rated 1 out of 5 by Stay away from steel bolts submerged under water!! I have been doing plumbing repairs for 20+ years. Never use brass plated galvanized steel bolts for INSIDE the toilet tank. They will rust up like you would not believe. I have included a picture below if you can see it. There is great risk of water damage from slow unnoticed leaks. Use brass only! The only downside with brass, its a bit softer than the steel bolts so you can't turn it like an idiot which you should not do anyway when you are dealing with porcelain. :-) August 29, 2013
Rated 1 out of 5 by Horrible quality!! horrible qualtiy - rusted within a day of installation. I had to remove and install a genuine brass (not brass plated like the Home Depot piece of junk). I will never buy plumbing hardware products from HD again. Cost me at least 1/2 hour addtional time to remove rusted bolts and replace with qualtiy bolts purchased at Warren Pipe. February 3, 2012
Rated 1 out of 5 by Why bother? One of the only reasons you would ever need to replace the tank bolts is the old ones were brass PLATED and not solid brass. The packaging says "BRASS" and in tiny letters says "plated". I made a MISTAKE buying these. They will either go in the trash or get returned. July 9, 2013
Rated 3 out of 5 by Smaller than OEM Bolt heads and washers smaller than OEM bolts on toilet. They are currently holding water, but it appears they will not last as long as the original as the sealing surface is much smaller. June 17, 2014
