When drilling a 2 x 4, what is the minimum distance from the edge to the hole?

1/4 inches
1/2 inches
5/8 inches
3/4 inches

The correct answer is: 5/8 inches

The minimum distance from the edge to the hole when drilling a 2 x 4 is important for maintaining the structural integrity of the wood. Drilling too close to the edge can compromise the strength of the material and lead to splitting or failure under load. In this context, a distance of 5/8 inches from the edge to the hole is typically recommended as it provides sufficient material around the hole to maintain strength while allowing for adequate clearance for screws or other fasteners that may be used in conjunction with the drilled areas. This distance helps to ensure that the drilling does not weaken the wood and contributes to the overall durability of the construction. Following proper guidelines, including this minimum distance, is essential for any construction project that uses dimensional lumber, such as a 2 x 4. Adhering to these recommendations is crucial for the safety and longevity of the completed structure.
