Closet bolts are often made of which material due to its corrosion resistance?

• A. Plastic
• B. Steel
• C. Brass
• D. Aluminum

Answer: (C)

Closet bolts are commonly made of brass because of its excellent corrosion resistance properties. In plumbing applications, particularly for toilets, these bolts must withstand exposure to moisture, various cleaning agents, and sometimes harsh environments that can lead to rust and deterioration over time. Brass, an alloy typically composed of copper and zinc, provides the necessary durability and longevity required in such installations, helping ensure a secure and stable toilet connection to the floor. Using materials like plastic can be viable for certain applications, but plastic may not provide the strength and stability needed for securing heavy fixtures. Steel, while strong, is prone to rusting when exposed to water unless it's coated, which can wear over time. Aluminum, while also lightweight and resistant to corrosion, does not offer the same strength as brass and may not hold up as well under the weight and stress conditions of toilet fixtures. Therefore, brass is the preferred choice for closet bolts, balancing corrosion resistance with mechanical strength.
