When attaching a water closet to a flange, what type of bolt should be used?

When attaching a water closet to a flange, it is essential to use corrosion-resistant bolts. This is due to the environment in which these bolts are utilized; water closets are often exposed to moisture, which can lead to rust and corrosion over time if unsuitable materials are used. Corrosion-resistant bolts, typically made from materials such as stainless steel with protective coatings or other alloys, will withstand this exposure much better than standard steel bolts.

Choosing corrosion-resistant options ensures a long-lasting and secure installation, reducing the need for maintenance or replacement of the bolts due to deterioration. This choice contributes to the overall durability and functionality of the plumbing installation and prevents leaks that can occur from bolts failing due to corrosion.

Other bolt types, such as standard steel, are prone to rust and can compromise the integrity of the installation. Plastic options may not provide the necessary strength or durability needed for the secure attachment of a water closet, and while stainless steel bolts are greatly resistant to corrosion, those that are specifically classified as "corrosion-resistant" are designed to offer even greater assurance in damp environments. Thus, the use of corrosion-resistant bolts is the best practice when securing a water closet to its flange.
