1. Material and Coating Fasteners should be made from materials that resist corrosion and wear, especially if the finished product is subjected to moisture. Coated fasteners, such as zinc or epoxy-coated, can offer additional protection.

5. Easy to Remove In addition to being easy to install, hex head self-drilling screws can also be easily removed with the appropriate tool. This feature allows for adjustments or repairs without damaging the surrounding material, which can be particularly beneficial in multi-stage construction or renovation projects.

Conclusion

3. Environmental Factors The choice of materials for self-drilling bolts, such as coatings or finishes, should consider the environmental conditions they will face, including exposure to moisture or corrosive substances.

Expandable anchors, often known as expansion anchors, are fasteners designed to secure objects to solid materials such as concrete, brick, or stone. The fundamental principle behind their design is the ability to expand under pressure, thereby creating a secure grip within the base material. When installed, the anchor's body expands outward, locking itself firmly in place, making it suitable for heavy loads and dynamic forces.
