Another benefit of self-drilling screws is their resistance to corrosion. Many self-drilling screws are coated with materials such as zinc or stainless steel to protect them from rust and corrosion. This is particularly important when working with heavy steel components that are exposed to harsh weather conditions or corrosive environments. The corrosion-resistant coating ensures the longevity of the screws and helps maintain the integrity of the structures they are holding together.

Butterfly screws, also known as toggle bolts, are a type of fastener that features a pair of wings that fold during installation and expand once they are inside a pre-drilled hole. The design allows for a stronger grip on hollow walls, such as drywall, where regular screws might not provide sufficient anchoring. Butterfly screws are particularly useful for mounting heavier items like televisions, where the risk of falling can be a significant concern.

The design and selection of aircraft structural fasteners are critical tasks that require meticulous attention to detail. Factors such as weight, strength, corrosion resistance, and temperature tolerance are all taken into consideration Factors such as weight, strength, corrosion resistance, and temperature tolerance are all taken into consideration Factors such as weight, strength, corrosion resistance, and temperature tolerance are all taken into consideration Factors such as weight, strength, corrosion resistance, and temperature tolerance are all taken into considerationaircraft structural fasteners. For instance, lightweight materials like titanium are often preferred for their strength-to-weight ratio, while stainless steel fasteners offer superior corrosion resistance.
