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.

4. Versatile Applications Hex screws are suitable for a wide range of woodworking applications, whether it’s constructing furniture, building cabinetry, or creating outdoor structures such as decks. Their robust design makes them ideal for both indoor and outdoor projects, where resistance to corrosion and weathering is a key factor.

4. Corrosion Resistance Many wafer head reamer self-drilling screws are available with protective coatings, such as zinc plating or galvanized finishes. These coatings increase resistance to rust and corrosion, extending the lifespan of the fastening solution.
