Final answer:
Closet bolts are commonly made from stainless steel or brass due to their corrosion resistance, ensuring long-lasting durability in wet and humid environments like bathrooms.
Step-by-step explanation:
Closet bolts are often made of stainless steel or brass because they resist corrosion. Corrosion resistance is essential in plumbing fixtures to ensure longevity and reliability. Stainless steel and brass are materials that do not easily corrode or rust when exposed to water or humid environments, making them ideal for use in bathroom installations such as securing a toilet to the floor.Closet bolts are often made of stainless steel because they resist corrosion. Stainless steel is an alloy of iron, chromium, and other elements that forms a protective layer on the surface, preventing rust and corrosion. This makes it an ideal material for bolts used in damp or wet environments, such as around toilets or plumbing fixtures.
