Product Description Hillman round head machine screw toggle bolts are heavy duty hollow wall anchors designed for secure fastening in drywall, plaster, tile, and hollow block applications. These toggle bolts provide dependable support for mounting shelving, mirrors, curtain rods, and decorative fixtures where reliable holding strength is required. The spring-action wings expand behind the wall surface to create a strong anchor point, while the large bearing area distributes weight evenly inside the wall cavity for improved stability. This design makes them a reliable choice for heavy duty drywall anchor installations. Engineered in size 1/8 x 2 , this anchor bolt is suitable for thinner wall materials and medium-duty mounting projects. A pilot hole is required before installation for proper wing deployment. Each retail package contains 50 pieces for larger project applications. From the Manufacturer Toggle bolts come with spring-action wings and are intended for anchoring into hollow walls. The wing is designed to spread apart behind the base material upon installation for firm hold in hollow wall applications. The wing disperses the weight of the secured item over a larger area, increasing the weight that can be secured compared to a regular bolt.
