What is the lag screw size used for a 6" pipe?

When selecting a lag screw for securing a pipe, the size is primarily determined by the diameter of the pipe and the requirements set forth by applicable codes. For a 6" pipe, the recommended lag screw size is typically 1/2 inch. This size provides the necessary strength and support for the weight and potential loads associated with a 6" diameter pipe, ensuring proper installation and stability. It balances the need for securing the pipe without risking damage to it or surrounding structures, adhering to the specifications set by industry standards and practices.

Other options may not provide the appropriate strength or could be either too small to handle the loads or too large, which might complicate installation or lead to unintended structural issues. Understanding these specifications helps ensure safety and compliance in sprinkler fitting practices.
