All of the following are examples of internal manway hardware except?

• A. Football washer
• B. Slide fastener
• C. Half washer
• D. Bellville washer

Answer: (B)

The slide fastener is not classified as internal manway hardware. Internal manway hardware generally includes components that are used within the manway assembly to secure and seal it. Football washers, half washers, and Bellville washers are all designed to provide specific mechanical properties like load distribution or spring characteristics, making them suitable for internal use in maintaining the integrity of manways. In contrast, a slide fastener, commonly used in applications such as clothing or bags, serves a different function and is not intended for the structural requirements of a manway. Thus, it doesn't align with the characteristics that define internal manway hardware. Recognizing the specific functions of these components can help in understanding their applications and importance in different settings.
