Metal expansion nuts are essential fastening components widely utilized in various engineering and construction applications. Designed to accommodate the natural expansion and contraction of materials due to temperature changes, these nuts offer a reliable solution for maintaining the integrity of connections in environments where traditional fastening methods may falter.

4. Durability Made from stronger materials and often treated with corrosion-resistant coatings, such screws provide added longevity, particularly in humid environments, such as bathrooms or kitchens.

1. Standard Nail Expansion Anchors These are commonly used in light to medium applications. They typically come in various sizes to accommodate different nail diameters and lengths.

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.
