What material are closet bolts often made from to resist corrosion?

Closet bolts are typically made from brass to resist corrosion effectively. Brass, an alloy of copper and zinc, has inherent properties that make it resistant to rust and corrosion, especially in moist environments like bathrooms. This is crucial for maintaining the integrity and longevity of the bolts that secure toilets to the floor.

While steel is strong and widely used in various applications, it can easily corrode when exposed to water, which makes it less suitable for use in areas prone to moisture. Aluminum, although lightweight and resistant to corrosion in some cases, does not exhibit the same strength and durability as brass when used in high-stress applications like securing plumbing fixtures. Plastic, while resistant to corrosion, usually lacks the structural strength needed to provide a stable and secure connection for heavy fixtures like toilets. Therefore, the use of brass for closet bolts ensures reliability and durability in a corrosive environment.
