Which of the following is true about drilling holes in studs?

Drilling holes in studs can indeed weaken the structure if not done properly. When holes are drilled into the framing members, such as studs, it's crucial that the holes are located in appropriate positions (such as the center and not too close to the edges) to maintain the structural integrity. If holes are too large or too numerous, they can compromise the strength of the stud, potentially leading to issues with load-bearing capacity.

Proper techniques include adhering to guidelines provided by building codes or structural engineering best practices, which ensure that the drilled holes do not exceed size limits or specific placement recommendations. This reinforces the idea that while it is sometimes necessary to drill into studs for running electrical wiring or plumbing, it should always be done with caution and knowledge of the potential impacts on structure strength.
