A TOGGLE refers to a specific type of fastener used to secure objects to materials that are typically too brittle or weak to hold screws or bolts on their own, such as drywall, plaster board or ceiling.
Purpose: Toggles create a secure point of attachment where regular screws or bolts would fail or pull out due to insufficient material strength.

– Plugs are tap-in anchors, which need pre-drill a hole with a specific drill bit. The objects are fastened together by screws or bolts and plugs, which are fixed together by friction with the materials. This friction is usually enhanced by the expansion of the plugs, but excessive expansion of the plugs will damage the board. The objects and the board are not fastened together directly.

– Screw-in anchors are generally self-drilling and are convenient to use because they are faster to install than plugs that need to be pre-drilled with a specific drill bit. To a professional or a Do-It-Yourselfer, time savings mean a lot! There are situations, however, where self-drilling may be more suitable for ANCHOR than pre-drilling and for smaller hole diameters. The larger the hole, the greater the damage to the drywall. Screw-in anchors rely primarily on the threads rather than just friction to hold the drywall together.

– Toggle is an enhanced version of Anchor. The toggle is the folding, mechanic-loaded part of the fastener that opens behind the material (i.e. hollow wall) to anchor the fastener securely.

– Shear force
Stationary objects that are attached to vertical walls need to withstand shear forces. These objects are generally not taken down and hung up, such as thermostat, clocks, picture frame, etc.

– Tensile force (Pull Out)
Hang objects from the ceiling.

– Cantilever force
If the bracket is at a certain distance from the wall, or if thick objects are hung on the wall, the hanging force is a combination of shear force and tension. Frequently  placed objects, such as paper towel bar, towel or cloth racks, and cabinets, will also be subject to the combined effects of shear force and tension.
Understanding the various load forces that affect wall toggle points can help you hang objects with more confidence.

– Using multiple anchors
When using multiple toggles, the damage to the gypsum board caused by the toggles themselves must be considered. When two or more fasteners must be used at a close distance, it is recommended to use a light anchor and a heavy toggle, which is also less cost.

– Working load
The vibration or shocks applied to working load applications can cause anchors to fail at lower values. It is recommended to use TOGGLE instead of ANCHOR.
