What Are Self-Drilling Metal Screws?

Applications of Stainless Steel Foundation Bolts

Due to their unique advantages, 2% self-drilling screws find applications in a wide array of sectors. In the construction industry, they are regularly used for securing metal roofing and siding, providing a strong hold that withstands weather elements. In the automotive industry, these screws assist in assembling parts securely without compromising the integrity of the materials involved.

Metal expansion nuts, often referred to as expansion anchors or expansion inserts, are specialized fasteners that expand when a bolt or screw is threaded into them. They typically consist of a cylindrical body with slits along its length or an expandable design that facilitates outward expansion. The main purpose of these nuts is to create a secure grip within a substrate, such as concrete, wood, or metal, thereby preventing loosening due to vibrational forces, temperature fluctuations, or stress.
