1/4 " or 5/16" T-Bolts?

Brawndo Plumbor · Jan 11, 2010

What do professionals prefer 1/4" or 5/16" T-Bolts for toilet to flange installation?

Anyone ever have luck with the snapoff type giving them the correct length?

Sorry I know this is a real Brawndo type of question but I have found little about it.

Functionally there is no difference. You are not trying to keep a truck from pulling the toilet off the floor. All the bolts do is secure it to the flange. Anything that would damage a 1/4" bolt would also break the toilet.

Any will work fine. I go the extra step and secure the johnny bolts to the closet collar with washers and bolts. This way the bolts are secure and wont move around when setting the bowl.

More important, with the additional nuts and washers, the bolt will not spin when you try to take the toilet up.

5/16", always.

I'm going to start using the tall caps so I don't have to cut the bolts off anymore.

Seems to me that toilet manufactures include 1/4" bolts with their toilets, and as HJ points out, all you are trying to do is hold the thing securely in place. I always use and extra washer and nut to hold the bolts firmly upright for ease of aligning the toilet. I don't like those snap off bolts. I put the washers and nuts on the long bolts and cut the bolts after tightening the nuts.

Either size works, just be sure they are solid brass and not plated steel.
