What is a Johhni bolt, how much does it usuallly cost, where is it used installing a tiolet?

I am sorry, I am not familiar with this terminology. However, you may be referring to either brass bolts that hold toilet bowl to the floor ( actually to the closet ring ) or to the bolts that attach toilet tank to the bowl.

In both cases they are sold in pairs and cost no more than $5.00 per pair. You can buy them in Home Depot or Lowe's.

Hi Mike...

Johnni bolts are the bolts used to hold the toilet BOWL to the closet flange of the plumbing waste pipe.

These bolts are installed into slots in a closet flange, then a wax gasket is added and toilet bowl is set in place and johnni bolts are tightened down. They get cut and capped to finalize project.

See picture below to see what they look like... they come in 1/4" size and 5/16" size.

I have also included a picture of a closet flange with johnni bolts inserted into slots.

After bowl is set then tank is added and hooked to water supply.

Johnni bolts cost about $2.00 or about $5.00 sold with a wax gasket. Any other questions, just pop back in and let us know...
