Which kind of drywall or hollow wall anchor comes in the largest diameter?

Toggle bolts are known for their ability to support significant weight while providing a secure anchoring point in hollow walls, such as drywall. Their design includes a pair of metal wings that open up behind the wall once the bolt is inserted through the wall and tightened. This creates a large surface area against the back of the wall, which allows toggle bolts to withstand heavy loads without pulling through the wall material.

In terms of size, toggle bolts typically come in various diameters and lengths, with some of the larger options reaching a diameter that is greater than what is commonly found in other types of anchors, such as plastic anchors or self-drilling anchors. The reinforced design and the expansion mechanism of toggle bolts enable them to handle greater weight capacities, making them ideal for applications where heavy objects need to be hung from hollow surfaces.
