A typical anchor used for heavy loads is called?

The typical anchor used for heavy loads is a regular toggle bolt. This type of anchor is specifically designed to support substantial weight and provide secure fastening in hollow walls, which may not be able to support standard screws or other types of anchors without additional assistance. When a toggle bolt is inserted into a wall, its wings expand and lock against the back of the wall, creating a strong point of anchorage that can handle the increased stress associated with heavier items.

In contrast, the other choices serve different purposes. A finishing nail is primarily used for light tasks like trim work and does not provide significant holding strength for heavy loads. A screw anchor is typically used for medium to light loads and may not offer the same level of support as a toggle bolt in hollow wall scenarios. A plastic anchor is also suited for light loads, as it provides minimal grip in the wall and is not designed for heavy-duty applications. Thus, the toggle bolt stands out as the most reliable choice for anchoring heavy loads securely.
