The recommended fastener spacing for built-up corner studs in a wood wall is typically based on ensuring sufficient strength and stability for the structure while minimizing the risk of failure under load. A spacing of 24 inches on center is often specified for built-up corner studs because this distance accommodates the necessary support for typical wall sheathing and allows for the distribution of loads without over-placing fasteners, which could lead to potential weaknesses.

In residential and light commercial construction, 24 inches on center is a common standard for stud spacing in non-load-bearing walls and can be adjusted based on specific engineering requirements or local building codes. This spacing also facilitates ease of construction as builders can lay out the studs in a consistent manner that aligns well with other building components like drywall or siding, optimizing material use and structural integrity.

Other spacings like 12 inches, 16 inches, or 20 inches on center may provide additional support but are not typically necessary for the applications of built-up studs unless specified by specific engineering conditions or building codes. In most cases, the design and structural assessment determine the minimum requirements needed for installations, emphasizing why 24 inches on center is a standard recommendation.
