1. Load-Bearing Capacity The higher the percentage, the greater the load-bearing capacity of the bolt. This means that 4% anchor bolts can secure heavier fixtures or withstand larger forces compared to 3% bolts.

5. Test Before Full Load After installation, gently test the anchor by applying light pressure before fully loading it with the intended object to ensure it has secured properly.

The white wafer head of these self-drilling screws is characterized by a broad, flat surface that provides a wide bearing area. This design helps distribute the load more evenly, reducing the risk of damage to the material being fastened. The head is typically finished in a white coating that not only enhances aesthetic appeal but also offers a degree of corrosion resistance, which is particularly beneficial in outdoor applications or areas exposed to moisture.

2. Self-Drilling Capability With their sharp, pointed tips, galvanized Tek screws can effortlessly penetrate metal and wood, eliminating the need for additional drilling tools. This feature contributes to faster installation and reduces labor costs.
