What is the maximum size for a drilled hole in a 2 x 6 joist, drilled 2 feet from the edge?

The correct choice regarding the maximum size for a drilled hole in a 2 x 6 joist, drilled 2 feet from the edge, is 1-1/2 inches.

In standard building practices, there are specific codes that dictate how to drill holes in joists to maintain their structural integrity. For a 2 x 6 joist, which typically has an actual width of 5-1/2 inches, the general guideline allows for a maximum hole size that ensures enough material remains to support loads.

Specifically, when a hole is drilled in the middle third of the joist span and at a distance greater than 2 inches from the edge, the maximum diameter of the hole can be up to 1-1/2 inches. This size balances the need for utility access with the joist's structural requirements, ensuring that the joist can still adequately support the loads it is designed to carry.

The other sizes provided exceed the safe drilling specifications, as larger holes could compromise the strength and load-bearing capacity of the joist, potentially leading to structural issues. Keeping within the maximum limit is crucial for safety in construction. Therefore, the choice of 1-1/2 inches is the right answer based
