stainless steel self drilling metal screws

Expanding drywall anchors, also known as toggle bolts or pop-in anchors, are designed to provide a strong hold in hollow walls such as those found in most residential homes. They consist of a thin metal sleeve with a spring-loaded expansion mechanism inside. When the anchor is inserted into a pre-drilled hole and a screw or bolt is tightened, the expansion mechanism opens up, gripping the wall material and providing a secure hold.
