Screws are another essential type of structural fastener, distinguished by their helical threads. They provide excellent holding power when driven into materials like wood, metal, or plastic. Common screw types include wood screws, machine screws, and self-tapping screws. Wood screws are designed specifically for use in wooden materials, while machine screws are used in conjunction with nuts or tapped holes in metal. Self-tapping screws, on the other hand, create their own thread as they are driven into the material, eliminating the need for pre-drilling.

Plastic butterfly wall anchors are small, plastic devices that are used to secure objects to the wall. They are designed to be inserted into the wall and then tightened to hold the object in place. What sets these anchors apart from other types is their butterfly-like shape, which adds a whimsical and decorative touch to the wall. In addition to their aesthetic appeal, plastic butterfly wall anchors are also quite practical and easy to use.
