What is the recommended maximum size of anchor rod hole for a 1 inch diameter anchor rod?

The recommended maximum size of the anchor rod hole for a 1 inch diameter anchor rod is indeed 1-13/16 inches. This size ensures a proper fit while allowing for sufficient space for installation and potential adjustments. The spacing is critical as it allows for the necessary bonding with the concrete and helps maintain the integrity of the structure being supported.

The recommendation is based on industry standards that aim to prevent excessive movement and misalignment of the anchor rod during installation, which could compromise structural stability. Additionally, it helps in ensuring that the rod can be properly tensioned and secured, which is essential in applications requiring high load-bearing capacities.

In contrast, other hole sizes may either exceed the desirable margin, potentially leading to a weaker connection or not allow for the necessary adjustment needed during installation. This is why the specific measurement of 1-13/16 inches is optimal for this size of anchor rod.
