What diameter clamp bolts are used for 8" pipes?

For 8" pipes, the appropriate diameter for clamp bolts is 3/4 inch. This size is specified by industry standards to ensure proper clamping force and secure connections for the fittings and joints in fire service mains. Properly sized bolts not only promote effective installation but also maintain the system's integrity under pressure conditions, which is critical for safety and reliability.

Using the correct bolt diameter is essential because it directly affects the ability of the connection to withstand operational stresses and prevent leaks. The 3/4-inch bolts are designed to align well with the components associated with 8" piping, providing sufficient strength without risking damage to the pipe or fittings. The other options do not meet the industry standards set forth for this type of installation.
