3. Plastic Expansion Anchors These are lightweight anchors often used for lighter objects in drywall. They consist of a plastic body that expands when a screw is inserted, providing a reliable grip for small shelves, frames, or lightweight decorations.

At its core, the structure of a bolt consists of a few key components the head, the shank, and the threads. The head is the larger, often hexagonal or square part at one end of the bolt, designed to provide a surface for the application of torque when tightening or loosening the bolt with a wrench. The shank is the long cylindrical part that spans between the head and the threads, and it determines the overall length of the bolt. The threads are helical ridges that spiral around the shank, allowing the bolt to engage with a nut or a threaded hole, enabling a strong clamping force between joined parts.

Butterfly screws, also known as toggle bolts, are a type of fastener that features a pair of wings that fold during installation and expand once they are inside a pre-drilled hole. The design allows for a stronger grip on hollow walls, such as drywall, where regular screws might not provide sufficient anchoring. Butterfly screws are particularly useful for mounting heavier items like televisions, where the risk of falling can be a significant concern.

4. Ease of Use Self-tapping screws can save time and reduce the risk of damaging the chipboard during assembly, making them a popular choice for both professionals and DIY enthusiasts.

Benefits of Using 1% 201% 4% Wafer Head Screws

Countersunk chipboard screws are specialized fasteners designed for joining chipboard and other materials. Unlike traditional screws, these screws feature a tapered head that allows them to sit flush with the surface of the material when installed. This design is particularly beneficial for aesthetic purposes and ensures that the screw does not protrude, which can be a safety hazard and may affect the finish of the project.

5. Ease of Removal In addition to installation, hex head self-drilling screws are designed for easy removal. Their hexagonal head allows for quick application of force using wrenches, making disassembly as simple as assembly when the need arises.

Wafer head screws are distinguished by their low-profile, flat heads, which provide a sleek finish and minimize protrusion above the surface. The designation 1% 201% 4% refers to specific mechanical and material properties that make these screws particularly effective in certain applications. The combination of these percentages generally relates to the composition of the screw materials and their tensile strength.
