One of the primary benefits of using expanding metal wall anchors is their high load-bearing capacity. Compared to plastic anchors, metal anchors provide superior support, especially for heavy items like shelves, TVs, or large picture frames. Their expansion mechanism also ensures that the load is evenly distributed, which minimizes the risk of the wall cracking or the anchor pulling out.

Understanding Hex Head Self-Tapping Screws with Washer Key Features and Applications

The installation process for self-drilling anchor screws is relatively simple. The pointed tip of the screw acts as a drill bit, allowing it to easily penetrate the surface material. As the screw is driven into the material, the threads on the shaft create a secure hold. Once the screw is fully inserted, the anchor portion expands behind the surface material, providing additional support and stability.

1. Ease of Installation One of the most significant benefits of self-drilling screws is their simplicity. With a hex head design, they can be quickly installed and tightened using a wrench or a power tool, which can improve efficiency on the job site.

5. Nut and Washer Compatibility When using M20 bolts, it’s crucial to pair them with corresponding nuts (usually M20 nuts) and washers. This combination ensures a secure fit and distributes the load evenly, minimizing the risk of loosening over time.
