Toggle Bolt

Definition

A toggle bolt is a bolt and nut assembly used to fasten objects to hollow construction assemblies from only one side. The nut has pivoted wings that close against the spring when the nut end of the assembly is pushed through the hole and spring open on the other side in the void of the construction assembly.

Purpose

The primary purpose of a toggle bolt is to provide a secure fastening solution in hollow walls or ceilings where traditional bolts or screws would not be effective. The expanding wings provide a strong anchor inside the hollow space.

Examples of Use

1. Drywall: Toggle bolts are commonly used to hang heavy objects such as mirrors, shelves, and artwork on drywall.
2. Ceilings: They are used to secure fixtures, such as light fixtures and ceiling fans, to hollow ceiling constructions.
3. Partition Walls: Toggle bolts provide strong fastening in hollow partition walls for mounting cabinets or heavy equipment.

Notes

• Installation: Proper installation involves drilling a hole, inserting the toggle bolt with the wings closed, and then tightening the bolt to open the wings and secure the fastener.
• Weight Limits: Toggle bolts are rated for different weight capacities, and it is important to choose the appropriate size for the intended load.
