2. **Environmental Friendliness** Traditional screws require a nut or washer to secure them, which can lead to waste if not properly disposed of. Hex head self-tapping screws, on the other hand, require no additional components, reducing waste and environmental impact.

One of the key advantages of using galvanized hex head bolts is their ability to withstand high levels of tension and shear force. The hexagonal head design allows for easy tightening and loosening with a wrench or socket, while the zinc coating ensures that the bolt maintains its structural integrity even under extreme conditions. This makes them an ideal choice for applications such as construction, automotive, and heavy machinery manufacturing, where strength and reliability are paramount.

Secondly，the desired holding power is another important factor to consider when selecting the correct wedge, bolt, and drill size. The holding power of a fastener is determined by its diameter, length, and thread pitch. Generally speaking, larger fasteners with higher thread pitches provide greater holding power. However, it's important to ensure that the fasteners you select are appropriate for the thickness of the material being fastened. If the fasteners are too large for the material, they may not be able to penetrate the material fully, resulting in reduced holding power.

The incorporated washer, on the other hand, serves multiple purposes. Primarily, it increases the bearing surface, thereby distributing the load from the screw more evenly across the material it's screwed into. This prevents damage to the surface, such as splitting or indentation, which can occur when a screw is tightened without a washer. Additionally, the washer can also help in reducing friction and preventing loosening due to vibration.

Self-fastening bolts, also known as self-locking or self-securing bolts, are typically made from high-strength materials such as stainless steel, carbon steel, or titanium alloys. They come in various sizes and styles, each tailored to meet specific industrial demands. For instance, some are designed with a built-in collet that grips the inner walls of the hole when tightened, creating a secure hold without the need for additional components. Others may feature an expandable sleeve that flares out at the end of the shank, anchoring the bolt firmly in place upon insertion.

3. Pre-drill Holes To prevent splitting or cracking of the roof material, pre-drill holes before inserting the screws. The diameter of the drill bit should be slightly smaller than the diameter of the screw shank.
