Final answer:
Toggle bolts use a spring-loaded catch to securely anchor objects to walls or ceilings by springing out and biting into the back of the surface.
Step-by-step explanation:
Toggle bolts use a spring-loaded catch to spring out and "bite" into the back of a surface. This allows them to provide a secure anchor point when attaching objects to walls or ceilings. They work by toggling behind the surface and expanding to grip the material. This is especially useful when screwing into materials like drywall or plaster that may not be strong enough to support a heavy load on its own.
