FAQ
How much weight can a toggle bolt hold?
On 1/2 in drywall, a 1/4 in toggle can hold roughly 50–100 lb (tension) depending on wall condition. Toggler-style toggles exceed 200 lb. Derate for shear and dynamic loads.
Can you remove a toggle bolt?
You can remove the bolt, but the wings fall behind the wall and are lost, so the hole must be patched. Toggler-style anchors stay captive and can be reused.
