What is the minimum diameter for toggle bolts used in plywood installation?

For plywood installation, the minimum diameter for toggle bolts is indeed 0.25 inches. Toggle bolts are used to anchor heavy items to hollow walls and ceilings, and their design allows them to provide strong support by distributing the weight across a larger area. A minimum diameter of 0.25 inches ensures that the toggle bolt can adequately engage with the plywood, offering sufficient grip and load-bearing capability without risking damage to the material.

Using a diameter smaller than 0.25 inches may not provide enough strength to hold significant weight, while larger diameters may be unnecessarily cumbersome for typical applications. This specification is crucial in installations requiring structural integrity and safety, ensuring that the toggle bolt performs effectively in holding the plywood to the supporting structure.
